Bug about the LINE_P function

[Tim Wessman]

As part of the move the RGB8888 we went through and reviewed all of the alpha and drawing routines.

Neither of the things you report behave any differently then what I'd expect looking at your simple code. The first draws a single blue line. If you move the black one over to x=99 you see a black line right next to the blue line.

The other doesn't do anything. If you change the alpha AA or something the screen gets a slightly darker shade.
