Textures with transparency and glBlendFunc

[James W. W. <ja...@wr...>]

I was puzzled to observe that an object with an ARGB texture did not 
become invisible, except for specular highlights, when the alpha 
channel was zero.  Apparently this is because Quesa uses 
glBlendFunc(GL_ONE, GL_ONE_MINUS_SRC_ALPHA) for transparent textures. 
Is there some good reason for this?
