GLContext return invalid_enum for:
CopyTexImage2D(this=0x000000012a621800, target=GL_TEXTURE_CUBE_MAP_POSITIVE_Y, level=0, internalFormat=GL_LUMINANCE, x=0, y=0, width=0, height=0, border=0)

The current framebuffer format is rgb8. I think the GL_LUMINANCE format is valid for rgb8.

I'm trying to simplify the test case.

[Christoph Diehl [:posidron]]

Yes, thanks for reducing the testcase, I was hoping it would be a simple error and you could figure it out easily.

This is probably bug 1290634.

Cool, Jeff!
gles2 have GL_LUMINANCE, but core profile doesn't support that. That's why there is an invalid_enum error.
There is no assert with the patch in bug 1290634.

Conformance tests now cover this.
