Re: [pygame] help with opaque images

[Ian Mallett]

In PyOpenGL, you'll either want to do a call to ortho, or set up another
viewport.  The viewport is specified from the bottom left corner of the
screen (as opposed to the top), so if your screen is 800x600, then
glViewport(700,500,100,100) sets up a 100x100 window for you to draw in in
the bottom right of the screen.  In one of my (currently unreleased) games,
there is a 3D radar in the top right of the screen done this way.  I've
never used ortho, though...
