Whoops, actually set the SDL error, don't just print the 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.

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.

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

Include the endpoint in the line we're drawing

Adjust the vertices to be over the texel center.
