Added comment for pixel-perfect line workaround.

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.

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!

pixels don't need to be dynamically allocated

SDL_RenderReadPixels() needs to flush asynchronous operations before it reads.

Support for UTF-8 text input has been added.

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.
