Increased tolerance a little bit more for multiple blending passes accumulating error.

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.
...
If we have to, we can use vertical line and horizontal line textures for vertical and horizontal lines, and then create custom textures for diagonal lines and software render those. It's terrible, but at least it would be pixel perfect.

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.

Use 45 degree lines for the diagonal test to avoid aliasing errors in line drawing.

It's not the last pixel, it's the rightmost pixel, or if they're both the same x coordinate, the bottommost pixel.

RenderReadPixels and RenderWritePixels functions work with back buffer now and all asynchronous operations are flushed before reading or writing to backbuffer. Thanks Sam for clarification of this.

My first OpenGL shader! Momma will be so proud!
...
This shader implements the software renderer mask semantics where the source pixel is multiplied by the color and alpha modulation values and then any pixel with non-zero alpha is fully opaque.
The OpenGL renderer on Mac OS X now passes all the automated render tests! :)

SDL_RenderReadPixels() needs to flush asynchronous operations before it reads.
...
The semantics are that it reads the back buffer, and those pixels may not be available once SDL_RenderPresent() has happened.

1. SDL_RenderPresent() call has been added after each test to be sure, that all graphics output is flushed in case if it was asynchronous.

2. After each renderer test window recreation has been added.

Hello Sam!
You have reverted back my patches for OpenGL renderer :)
To reproduce an issue, compare graphics output while running these tests:
testdraw2 --renderer opengl --blend mask --cyclealpha
and
testdraw2 --renderer software --blend mask --cyclealpha
You will see, that software renderer output is different from opengl renderer output.
Thanks!
