I''m working on a couple of 3d-intensive (OpenGL) screen savers. Since my desktop is 1600x1200 (and I know a lot of folks tend to run very high-res desktops in general) and by and large the graphics I''m using are rather slow at those sorts of resolutions, I''d really like to change the resolution as part of my screen saver''s initialization, and then change it back when the saver exits. Is this really kosher to do (I know that some programs that change resolutions seem to have a habit of moving or clipping windows), and if it is is there a way of doing it ''right'' such that the user''s desktop when the saver exits will be exactly what it was before the saver was run?
