But, for now, I'll try WritePixel. If that isn't good enough, I'll just make a few fixed color crosshairs and live with it.
Good luck! I would recommend Ross C's advice then, and use a single bitmap with multiple frames
I wonder why there isn't a color command for images...you'd think it would be the same process that occurs to textures when you use entitycolor()...
I think it's due to the way 3D objects are rendered. Similar to how they become mipmapped/aliased and have light effects altering their apparent colour. An image is just an image and maybe is more required NOT to change color at all!
