- fixed alpha texture generation for OpenGL rendering.

Browse source 
The old logic used a translation table that does not work with color images, it was designed to handle 8 bit grayscale images.
So now, it creates a true color buffer and then turns it into a texture with R,G,B = 255 and the alpha channel set to the grayscale value.

This was also the reason why crosshairs made from 32 bit PNGs did not show correctly.
