GL_CONSTANT_ALPHA not available in OpenGL ES 1.0

Hello

Why GL_CONSTANT_ALPHA constant is not available on OpenGL ES 1.0?

It was more a question whether this is a bug or not.
However, I like seeing users using bugzilla a lot nowadays, thank you!

So looking in the spec, it's not - i.e. not existing.
As w/ your other bug reports, all invalid,
please validate w/ the spec first, i.e. ES1:

http://www.khronos.org/opengles/sdk/1.1/docs/man/
http://www.khronos.org/registry/gles/specs/1.1/es_full_spec_1.1.12.pdf

https://jogamp.org/bugzilla/show_bug.cgi?id=618 .. etc
