[Piglit] [PATCH 07/11] fbo-gl_pointcoord: remove config.window_width/height and fix asst. bugs

[Brian Paul]

The size of the window and the size of the FBO were mixed up in a few
places.  Add missing FBO binding calls so the window can be resized.
Use an rb_size variable instead of hard-coded 100.
