Add Shader Configuration panel. #32
Description
It's a good idea to have added a default shader. May be you can add some of them.
Shaders can be configured to match for your best experience, but it's a pain... Can you add a way to configure the defautl shader, crt-guest-cgwg-curvature ?
May be add default parameters for CGA, MDA, EGA, VGA CRT monitors.
