The basic rule of thumb is that if you draw anything with opengl (especially if it involves textures, alpha transparency, depth buffer, lighting, or fog) it will run very slow unless you have actual 3d hardware acceleration. So, it may be possible to do a 2d panel that runs fast on 2d hardware, but probably not with opengl, and definitely not with the subset of opengl we are using.
