Fonts now have strange artifacts in some instances

[conniefry]

With release 0.28, there is an issue rendering lowercase L and upper case i for some fonts and pixel sizes. The lower case L appears thicker, like it is wider than it should be.

To reproduce, run tests/text2tests.js
Hit 'f' key until the font used is IndieFlower.ttf (current font is displayed at bottom of screen)
Hit lowercase 'p' until pixelSize is 35 (current pixelSize is displayed at bottom of screen)
Hit 's' to change text displayed until text is "Hello! How are you?"

Notice the double Ls in "Hello".

This issue appears to have been introduced by commit d0135c6

A partial fix was done in 295fb9a. There is still some strangeness depending on the font and pixelSize.
