Title: GRAPHICS: Fix colorToARGB's alpha value when no alpha channel is present

When there is no alpha channel, it should return 0xFF to signify the color is opaque.

The reason I'm creating this pull request is because I don't know if this is "too hacky" to have in PixelFormat, not to mention it probably won't help with any sort of speed issue.
