Starting with the checker.c example;

If I set the color bits to 0 for black and the alpha channel to 127, I get gray colored textures.

Setting the alpha channel to 0, makes the texture appear white.

How do I get this texture to blend? I would expect that a black texture would appear black against a black background no matter the alpha values.

Looks like I was misusing the GL_RGBA setting.

if you look at gl.h

#define GL_RGBA GL_RGB

so it is weird, but good
