Thanks for the analysis!

The other way to deal with GL_ALPHA being removed:
glTexImage2D(GL_TEXTURE_2D, 0, GL_RED, w, h, 0, GL_RED,
GL_UNSIGNED_BYTE, pixels);
glTexParamateri(GL_TEXTURE_2D,
GL_TEXTURE_SWIZZLE_R,
GL_ZERO);
glTexParamateri(GL_TEXTURE_2D,
GL_TEXTURE_SWIZZLE_G,
GL_ZERO);
glTexParamateri(GL_TEXTURE_2D,
GL_TEXTURE_SWIZZLE_B,
GL_ZERO);
glTexParamateri(GL_TEXTURE_2D,
GL_TEXTURE_SWIZZLE_A,
GL_RED);
That will make it behave identically (for texturing) to an old GL_ALPHA
texture.
I'm going to close this as NOTOURBUG and work with Valve to get this resolved
in Dota 2.</pre>
