When using Mesa directly or with GLX, it's up to the application
writer to create a window with an appropriate colormap. The GLUT

+toolkit tries to minimize colormap <em>flashing</em> by sharing
colormaps when possible. Specifically, if the visual and depth of the
window matches that of the root window, the root window's colormap
will be shared by the Mesa window. Otherwise, a new, private colormap
