2017-08-04  Daniel Ferreira <dtf@stanford.edu>

	* Headers/ImageIO/ImageIO.h
	* Headers/ImageIO/ImageIOBase.h
	* Source/OpalGraphics/GNUmakefile.postamble:
	CGImageSource and CGImageDestination are not actually CoreGraphics APIs
	on the reference platform; rather, they are part of the ImageIO
	framework and should be installed on the system as such.

	However, simply transferring these two APIs from OpalGraphics into a new
	"OpalImage" subproject is not so easy, since they have developed in many
	ways a symbiotic relationship inside the library.

	As a workaround, a GNUmakefile.postamble file has been added to
	OpalGraphics which takes care of installing ImageIO headers properly.

2017-08-04  Daniel Ferreira <dtf@stanford.edu>

	* Source/OpalText/GNUmakefile:	
	A mistake in the addition of SFNTLayoutTypes.h omitted an entry in the
	project's GNUmakefile for it to be installed. This fixes the issue.

2017-07-26  Daniel Ferreira <dtf@stanford.edu>

	* Headers/CoreText/CoreText.h
	* Headers/CoreText/SFNTLayoutTypes.h:	
	Define SFNTLayoutTypes constants on CoreText for increased compatibility
	with Quartz.

2017-07-26  Daniel Ferreira <dtf@stanford.edu>

	* Headers/CoreText/CTLine.h
	* Source/OpalText/CTLine.m:	
	Add unimplemented stub to CTLine for increased compatibility with
	Quartz.

	* Headers/CoreText/CTFont.h
	* Source/OpalText/CTFont.m:	
	Add stubs for some CTFont* functions for increased compatibility with
	Quartz.

2017-07-26  Daniel Ferreira <dtf@stanford.edu>

	* Headers/CoreText/CTFont.h
	* Headers/CoreText/CTFontDescriptor.h
	* Headers/CoreText/CTFontTraits.h:	
	Update enumeration values for CTFont types, which have been updated in
	the latest versions of the reference platform.

2017-07-17  Daniel Ferreira <dtf@stanford.edu>

	* Tests/paths.m:	
	Improve the CGPath tests to cover more cases.

2017-07-17  Daniel Ferreira <dtf@stanford.edu>

	* Headers/CoreGraphics/CGPath.h
	* Source/OpalGraphics/CGPath.m:	
	Implement CGPathContainsPoint() with logic taken from GNUstep-GUI's
	NSBezierPath.
	
	Add an implementation to CGPathAddArcToPoint(), a Quartz function for
	creating curves in a convenient way.
	
	Implement CGPathCreateWithRect(), a function which create a CGPath from
	a rect.
	
	Implement CGPathCreateMutableCopyByTransformingPath(), a function which
	creates a new CGPath from another one by applying a transformation to
	its points.

2017-07-17  Daniel Ferreira <dtf@stanford.edu>

	* Headers/CoreGraphics/CGPath.h
	* Source/OpalGraphics/CGPath.m:	
	According to the Quartz specification, CGPathGetBoundingBox() should
	include Bézier control points in its return rectangle, while
	CGPathGetPathBoundingBox() should not.

	This commit creates CGPathGetBoundingBox() with the exact same behavior
	as the old Opal CGPathGetPathBoundingBox(), which mistakenly considered
	Bézier control points in its return value. It also rewrites
	CGPathGetPathBoundingBox() to exclude the control points from the return
	value as per the specification.

2017-07-12  Daniel Ferreira <dtf@stanford.edu>

	* Source/OpalGraphics/CGPath.m:	
	Rewrite the implementation of CGPathAddArc() to use the implementation
	provided by NSBezierPath in GNUstep GUI. This amends a number of bugs in
	its implementation, such as clockwise/counterclockwise handling.

2017-07-12  Daniel Ferreira <dtf@stanford.edu>

	* Headers/CoreGraphics/CGPDFDocument.h
	* Source/OpalGraphics/CGPDFDocument.m:	
	Add a stub for CGPDFDocumentGetPage() for increased Quartz
	compatibility.

2017-07-12  Daniel Ferreira <dtf@stanford.edu>

	* Headers/CoreGraphics/CGImage.h
	* Source/OpalGraphics/CGImage.m:	
	Define stubs for constants to get CGImage properties. This increases
	compatibility with Quartz.

2017-07-12  Daniel Ferreira <dtf@stanford.edu>

	* Headers/CoreGraphics/CGContext.h
	* Source/OpalGraphics/CGContext.m:	
	Implement CGContextPathContainsPoint() using Cairo fill functions. This
	improves compatibility with Quartz.

2017-07-12  Daniel Ferreira <dtf@stanford.edu>

	* Source/OpalGraphics/CGPath.m:	
	Fix badly indented parts of CGPath.m which gravely hindered the code's
	readability.

2017-07-12  Daniel Ferreira <dtf@stanford.edu>

	* .gitignore:	
	Make Git ignore *.orig and *.swp files, which are text editor
	byproducts.

2017-07-12  Daniel Ferreira <dtf@stanford.edu>

	* Headers/CoreGraphics/CGGeometry.h:	
	Define CGGeometry basic structs as equivalent to their NSGeometry
	counterparts. This allows them to be interchangeable as in the reference
	platform.

2017-07-11  Daniel Ferreira <dtf@stanford.edu>

	* Headers/CoreGraphics/CGColorSpace.h
	* Headers/CoreGraphics/CGContext.h

	* Headers/CoreText/CTLine.h
	* Headers/CoreText/CTParagraphStyle.h
	* Headers/CoreText/CTRun.h
	* Headers/CoreText/CTStringAttributes.h:	
	Remove `typedef enum` declarations from public Opal headers, which
	caused type errors if a client tried to bitwise-OR two values of
	different enum types, which is usually allowed per the API
	specification.

2017-07-11  Daniel Ferreira <dtf@stanford.edu>

	* Headers/CoreGraphics/CGPath.h:	
	Export `CGMutablePathRef` as `CGPath *`, and not `CGMutablePath *`.

	As per 083ef1d802d86db333fa40afeebaea7605737953 ("Opal: remove
	unnecessary casts", 2010-07-13), we have added @class
	forward-declarations for every internal Objective-C class that helps
	implement the CoreGraphics C API. This avoided the need for many casts
	inside the project, but caused conflicts when these headers were
	imported by other projects.
	Now, we guard against making this declaration in public headers unless
	we are actually building Opal.

	* Source/OpalGraphics/GNUmakefile
	* Source/OpalText/GNUmakefile:	
	Add a macro to determine whether we are building Opal.


2017-06-14  Daniel Ferreira <dtf@stanford.edu>

	* .gitignore:	
	Create a .gitignore file which causes Git to ignore products of the
	project (usually in obj/ folders) and avoids mistakenly adding them to
	the soruce tree.

2017-06-11  Daniel Ferreira <dtf@stanford.edu>

	* Headers/CoreGraphics/CGAffineTransform.h:	
	The lack of an `extern` directive on CGAffineTransformIdentity's
	declaration caused the compilation of C++ files that imported this
	header to fail. This commit amends the issue.

	* Headers/CoreGraphics/CGBase.h
	* Headers/CoreGraphics/CGColorSpace.h:	
	Despite the numerous __OBJC__ guards on CoreGraphics headers to attempt
	independency from Objective-C, Opal headers would still break any
	project that tried to build non-ObjC files that included CoreGraphics
	headers. We amend this issue here.

	* Headers/CoreGraphics/CGBase.h:	
	To get rid of a CoreBase dependency in Opal, all CF types used by the
	project were redefined in CGBase.h in r31020. However, this added the
	setback that any project that includes CoreBase *after* including
	CoreGraphics would have its build broken due to redefinitions, which is
	highly undesirable. We amend this issue here.

	* Headers/CoreGraphics/CGError.h
	* Headers/CoreGraphics/CoreGraphics.h
	* Source/OpalGraphics/GNUmakefile:	
	QuartzCore provides a CGError enum for tracking errors returned by the
	library, which we did not yet supply. This commit creates this
	definition for compatibility purposes.

2013-09-21  Ivan Vucica  <ivan@vucica.net>

	* Tests/GNUmakefile:
	* Tests/gstate.m:
	Added gstate test. Currently this tests whether some CTM
	operations are correctly performed in a CGContext; namely,
	setting identity CTM, concatenating, and getting the current
	CTM.

2013-09-19  Ivan Vucica  <ivan@vucica.net>

	* Source/OpalGraphics/CGContext+GState.m:

	flipping logic. gstate.m test now passes.

2013-09-21  Ivan Vucica  <ivan@vucica.net>

	* Tests/GNUmakefile:
	* Tests/gstate.m:
	Added gstate test. Currently this tests whether some CTM
	operations are correctly performed in a CGContext; namely,
	setting identity CTM, concatenating, and getting the current
	CTM.

2013-09-19  Ivan Vucica  <ivan@vucica.net>

2013-09-18  Eric Wasylishen  <ewasylishen@gmail.com>

	* Tests/bitmaps.m:
	* Tests/images.m: Move sub-image test to images.m.
	Draws a portion of World_Map_1689.jpg over the
	GNUstep logo.

2013-09-18  Eric Wasylishen  <ewasylishen@gmail.com>

	* Tests/cocoa.m:

	demo. Tweak window setting in cocoa.m.

2013-09-18  Ivan Vucica  <ivan@vucica.net>

	* Tests/bitmaps.m:
	Added code testing how sub-images are being drawn into CGContext.

	* Source/OpalGraphics/CGFont.m:
	* Source/OpalGraphics/internal/CGFontInternal.h:
	* Source/OpalGraphics/cairo/CairoFontWin32.m:
	* Source/OpalGraphics/cairo/CairoFontX11.m:
	* Headers/CoreGraphics/CGFont.h: Add private OPFontGetGlyphWithCharacter
	to get the glyph index for a character. The proper API is in CoreText
	but that's not usable yet, unlike CGFont.

2013-09-17  Eric Wasylishen  <ewasylishen@gmail.com>

	* Tests/texttest.m: Fix test: bug calculating glyph indicies
	with the wrong font.

2013-09-17 Eric Wasylishen  <ewasylishen@gmail.com>

	* Source/OpalGraphics/cairo/CairoFontX11.m (-descent): Fix
	descender calculation.

2013-09-17 Eric Wasylishen  <ewasylishen@gmail.com>

	* Source/OpalGraphics/CGContext.m (CGContextShowGlyphsAtPositions):
	Check if font size is 0, and log an error instead of continuing,
	which seems to put the cairo context into an error state.

2013-09-17 Ivan Vučica <ivan@vucica.net>

	* Headers/CoreGraphics/CGFont.h:
	* Source/OpalGraphics/CGFont.m:

	* Source/OpalGraphics/cairo/CairoFont.m:
	Added -createWithFcPattern: stub.

2013-09-12  Eric Wasylishen  <ewasylishen@gmail.com>

	* Source/OpalGraphics/CGContext+GState.m:
	* Headers/CoreGraphics/CGContext.h: Add OPContextCopyGState
	and OPContextSetGState. I know we discussed writing getters
	for individual properties of the graphics state but this
	was quicker to throw together as a first iteration.
	Warning, not tested.

2013-09-12  Eric Wasylishen  <ewasylishen@gmail.com>

	* Rename NSFont* to OPFont* to avoid conflicting with AppKit.
	This is just a quick hack; to enable toll-free bridging will
	require significant work.

2012-09-13 Ivan Vucica <ivan@vucica.net>

	* Source/OpalText/CTFramesetter.m:
	Breaking out of an infinite loop.

2013-08-02 Fred Kiefer <FredKiefer@gmx.de>

	* Tests/GNUmakefile: Get it to compile again

2013-07-25  Ivan Vucica <ivan@vucica.net>

	* Source/OpalGraphics/OPLogging.h:
	Changed NSDebugLLog() category to OpalCall.

	* Source/OpalGraphics/CGContext.m:

2013-07-24  Eric Wasylishen  <ewasylishen@gmail.com>

	* Source/OpalGraphics/CGImage.m (CGImageCreateWithImageInRect):
	Revert last change, it needs more work

2013-07-24  Eric Wasylishen  <ewasylishen@gmail.com>

	* Source/OpalGraphics/CGImage.m (CGImageCreateWithImageInRect):
	Use the source rect to set the returned image's size.
	The method is still incomplete, see TODOs.

2013-07-23  Eric Wasylishen  <ewasylishen@gmail.com>

	* Source/OpalGraphics/image/OPImageCodecPNG.m: Rewrite to use
	OPImageConvert and always convert to 32-bit RGBA, unpacked,
	non-premultiplied. This is not ideal, but should always work.
	* Source/OpalGraphics/CGDataConsumer.m: Create the file if
	needed.

2013-07-24 Ivan Vučica <ivan@vucica.net>

	* Source/OpalGraphics/CGBitmapContext.m:

	* Source/OpalGraphics/OPImageConversion.m:
	* Source/OpalGraphics/OPColorTransformLCMS.m:
	* Source/OpalGraphics/CGContext.m:
	* Source/OpalGraphics/CGAffineTransform.m:
	Most non-error logging is now using NSDebugLLog(), to have Opal emit less
	noise unless explicitly requested. Cleaned up small pieces of code.

2013-07-21 Ivan Vučica <ivan@vucica.net>

	* Source/OpalGraphics/OPLogging.h:
	* Source/OpalGraphics/OPLogging.m:
	Call logging macros.

	* Source/OpalGraphics/CGBitmapContext.m:

	* Source/OpalGraphics/CGImage.m:
	Fixed crash in case 'data' argument passed to DumpPixel() was null.

	* Source/OpalGraphics/CGContext.m:
	* Headers/CoreGraphics/CGContext.h:
	-Added OPContextSetCairoDeviceOffset().
	-Added logging to nearly all GContext*() functions.
	-In CGContextSet*ColorWithColor(), fixed retain/release setter
	 mechanics, so they don't break if user passes same CGColor pointer
	 twice.
	-Added checks for null context and null ctx->add in several (but not
	 all) places.

	* Source/OpalGraphics/CGBitmapContext.m: Fix subtle endianness bug.
	For future reference, kCGBitmapByteOrderDefault means big-endian.
	* Tests/bitmaps.m: Add a bitmap context test. It draws a black background
	with a cream colored blob in the bottom left.

2013-07-16  Eric Wasylishen  <ewasylishen@gmail.com>

	* Source/OpalGraphics/CGBitmapContext.m: Use calloc to allocate zeroed
	bitmap buffers

	* Tests/GNUmakefile,
	* Source/GNUmakefile: Allow for compilation without OpalText.
	To achieve this define the variable NO_OPALTEXT before compiling.

2011-03-23 Niels Grewe <niels.grewe@halbordnung.de>

	* Source/OpalText/FreeType/OPFreeTypeFont.m: Implement
	-glyphWithName:.

2011-03-15 Niels Grewe <niels.grewe@halbordnung.de>

	* Source/OpalText/FreeType/OPFreeTypeFont.m: Finish bounding
	rect retrieval.
	* Source/OpalText/NSFont.h
	* Source/OpalText/NSFont.m:
	Turn transformation matrix to a union so CGAffineTransform,
	NSAffineTransformStruct and the CGFloat array used by NSFont
	can be used interchangeably.

2011-03-15 Niels Grewe <niels.grewe@halbordnung.de>

	* Source/OpalText/FreeType/OPFreeTypeFont.m: Implement more
	transformations, some bounding box stuff.
	* Source/OpalText/NSFont.h
	* Source/OpalText/NSFont.m:
	Store the font matrix as an CGAffineTransform for convenience.

2011-03-15 Niels Grewe <niels.grewe@halbordnung.de>

	* Source/OpalText/FreeType/OPFreeTypeFont.m: Make FreeType
	handle text transforms (at least partially). Implement getting
	glyph advances.
	* Source/OpalText/FreeType/OPFreeTypeUtil.h: Add convenience
	functions for translating between CGAffineTransforms and
	FreeType vectors/matrices.

2011-03-14 Niels Grewe <niels.grewe@halbordnung.de>

	* Source/OpalText/FreeType/OPFreeTypeFont.m: Implement some more
	NSFont methods in terms of FreeType.

2011-02-20 Niels Grewe <niels.grewe@halbordnung.de>

	* Source/OpalText/FreeType/OPFreeTypeUtil.h: Also mark inline
	functions as static.

2011-02-20 Fred Kiefer <FredKiefer@gmx.de>

	* Source/OpalGraphics/CGContext.m: Add CMYK colour methods.

	* Source/GNUmakefile: Use := when setting ADDITIONAL_CPPFLAGS and
	ADDITIONAL_LDFLAGS to reduce the number of subshell invocations
	required to compile.
	* Tests/GNUmakefile: Same change for ADDITIONAL_LDFLAGS.
