glCopyTexImage2D does not respect BGRA extensions.

[GoogleCodeExporter]

What steps will reproduce the problem?
1.  Construct a texture with a BGRA format.
2.  Bind said texture as the colour buffer of a framebuffer object.
3.  Bind the framebuffer object as the read framebuffer.
4.  Attempt to perform a glCopyTexImage2D call.

What is the expected output? What do you see instead?

If the BGRA extension is supported, then glCopyTexImage should be able to 
succeed.

The routine explicitly allows RGBA-ordered formats, but does not include any 
BGRA enumerations:

This is by design.  There are no extensions supported (or defined for that 
matter) which add support for this.
The 
http://www.khronos.org/registry/gles/extensions/EXT/EXT_texture_format_BGRA8888.
txt extension (which ANLGE does support) only adds support for TexImage2D / 
TexSubImage2D.  

Support could be added, but that will require a new extension.

Works as intended. A new issue can be opened if an extension is proposed.
