Sat, 21 Nov 2009 07:46:12 +0000	Sam Lantinga	Increased tolerance a little bit more for multiple blending passes accumulating error.
Sat, 21 Nov 2009 07:26:52 +0000	Sam Lantinga	Added comment for pixel-perfect line workaround.
Sat, 21 Nov 2009 07:22:59 +0000	Sam Lantinga	Of COURSE that trick wouldn't work on all renderers. Fall back to something for now, hopefully figure out a better way to do this later.
Sat, 21 Nov 2009 07:14:21 +0000	Sam Lantinga	This is terrible, but the OpenGL standard says that lines are half open, which means that one endpoint is not covered so adjoining lines don't overlap. It also doesn't define which end is open, and indeed Mac OS X and Linux differ. Mac OS X seems to leave the second endpoint open, but Linux uses the right-most endpoint for x major lines and the bottom-most endpoint for y major lines.
Sat, 21 Nov 2009 06:34:43 +0000	Sam Lantinga	Fixed the coordinates for pixel coverage in blits
Sat, 21 Nov 2009 06:28:25 +0000	Sam Lantinga	Use 45 degree lines for the diagonal test to avoid aliasing errors in line drawing.
