Description
This is most noticeable with drop down menus.
Ideally, we would want to paint something, anything, even a white background rather than having it transparent and showing whatever is under it.
Unfortunately, my attempts have failed (see patches).

calls render_image as soon as we init the gl window (use in combination with gl_cairo_fill or gl_white_paint patches)

Mitigated somewhat by r3077: "normal" windows are bigger, so showing them briefly as transparent is less confusing than for things like menus.

What may work: calling glClear(GL_COLOR_BUFFER_BIT) followed by swap_buffers() early in the setup backing setup code.
Now that GL is no longer scheduled for 0.9.0, this can wait too..
