A few minor fixes:
- In FramebufferRenderbuffer, if renderbuffer isn't 0,
it must be a valid object.
- In FramebufferTexture2D, I moved the isCompressed check AFTER
the textarget validation, to avoid using an invalid textarget.
- In GetFramebufferAttachmentParameteriv, not using GL_BACK,
GL_DEPTH or GL_STENCIL for the default framebuffer should
produce GL_INVALID_ENUM instead of GL_INVALID_OPERATION.
- In GetFramebufferAttachmentParameteriv, when
attachmentObjectType is GL_NONE, in ES3, the query for
GL_FRAMEBUFFER_ATTACHMENT_OBJECT_NAME should return 0.
