    initial v1  
    33First a little background on Overlays: this is a feature of some video cards, that allows putting a separate image (usually a video) above the normal display. The overlay and main buffer are entirely separate, and can have different color spaces. The main use for this is playing a video file (usually in some YUV colorspace) over an RGB desktop, and letting the video card perform colorspace conversions.

    5 The support for overlays, and the supported colorspaces, is independant from the screenmode. So, I would do things like this:
    6 
    7 * {{{screenmode}}} (no options) shows the current screenmode. No changes here.
    8 * {{{screenmode -l}}} lists available modes. Again, no changes
    9 * {{{screenmode -o}}} lists available overlay colorspaces. It should try all colorspace constants (not just the 3 you have in the code), because overlays are most often used with YUV spaces.

    117Sorry about this, it should have been part of the task description.
