achievements.viewer not displaying properly

[MarcAlx]

Hi, thanks for your incredible work.

In my game I've found that achievements.viewer displays as a blank screen instead of the required UI.

To my understanding it's because I used to change setImageDrawMode to kDrawModeFillWhite.

If I call gfx.setImageDrawMode(gfx.kDrawModeCopy) just before achievements.viewer.launch() everything works as expected.

It'd be convenient if achievements.viewer.launch() saves actual getImageDrawMode then set gfx.setImageDrawMode(gfx.kDrawModeCopy) on its own to finally restores saved value on resume.

Are you using gfx.pushContext() and gfx.popContext() around any changes you make to the graphics context? The viewer itself does, so it should leave the external context just as it was. Right now I suppose the viewer is expecting an unmodified context before it starts drawing; it couldn't hurt to have the viewer assert the intended draw mode explicitly as a precaution since popping the context will restore its initial state either way, but I'll let @jonsimantov chime in since I haven't worked directly with that code.

I don't use context, do not hesitate to ask for further information.

[jonsimantov]

Yeah it should be pretty straightforward to set the image draw mode when the viewer starts up. If you'd like to put in a quick PR to fix it, we can get that in, otherwise I'll take a look at fixing it myself soon. Thanks for the report!

[MarcAlx]

No problem for a PR, it should be ok before tomorrow.

@jonsimantov Thanks for feedback after few test, this was needed. I add a gfx.setImageDrawMode(gfx.kDrawModeCopy) to drawCard of toasts.lua
