most Gem object could be replaced by GEMgl* stuff...

i do not agree. 
using shader, how would you do :
GL_ONE_MINUS_SRC_COLOR
you need the source color. a readback is not an option.

moreover, it's lot's easier to try sending diferent number in the alpha object to see the result, than to write a shader.

and if you don't need this functionality, you don't have to use it...

So,i think it would be nice to have this small modification included in Gem.
