gl.BindFramebuffer missing

[nergdron]

glBindFramebuffer seems to be missing from these bindings. There is a generic Buffer.Bind() function, but internally it uses glBindBuffer, and so passing in valid enums for glBindFramebuffer just results in a GL_INVALID_ENUM error.

I need glBindFramebuffer so I can use gl.BlitFramebuffer, which does have bindings here, but doesn't work properly without being able to bind separate gl.READ_FRAMEBUFFER and gl.WRITE_FRAMEBUFFER.

Try 'func (fb Framebuffer) BindTarget(target GLenum)' instead (https://github.com/go-gl/gl/issues/113). Bind() method doesn't reflect functionality of glBindBuffer since it sets target to GL_FRAMEBUFFER. Don't know why it is implemented this way. However this could be fixed by adding target parameter to Bind() method and replacing it in old code with Bind(gl.FRAMEBUFFER).

Hmmm, I had an older checkout of go-gl/gl that didn't have this function. It looks like it'll require a patch to use with glh.Framebuffer, but it's what I was after. Thanks for the tip!

@pakanek In answer to your question, I think it was a mistake in the original bindings that it was hard coded and not a parameter. We're going to some lengths to maintain API compatibility so we can't just add another parameter - that would break code in the wild which uses it. Hence the new function.
