I think it could use a better name like
al_[set/use/enable/mask/disable/...]_color_channels() because alpha
isn't a color and "mask" sort of implies something more configurable
than simply on/off.

Anyway as long as it returns true/false or there is some way to detect
whether or not it is supported given the current target or driver,
then it seems like a reasonable function assuming both D3D and OpenGL
have at least some support for it. (The docs sound as if it is driver
dependent on D3D.)
