#X text 22 91 [alpha] turns on and off alpha blending. [alpha] automatically
uses the glBlendFunc(GL_SRC_ALPHA \, GL_ONE_MINUS_SRC_ALPHA) function
from OpenGL. If you want a different blending technique \, you will
need to make your own external. The blending that [alpha] does is the
stereotypical blending which you will usually want. In a nutshell \,
any pixel which has an alpha component will be blended with the pixel
that is in the frame buffer \, producing the usual colored glass effect.
Be aware that the rendering order matters \, so you probably want to
set the gemhead order number high so that the object is rendered after
all of the non-alpha blended ones.;
