I don't have a complete list, but recent nvidia chips and the r128 have a second hardware cursor, and many recent chips have a full-color cursor (64x64x32bpp) (nvidia, the entire radeon line). > Well, some card have upto 4 channels, main, overlay, underlay and > cursor.

I'm curious how they get drag icons to drag so solidly even when they are big. (group select a bunch of files and drag them and the drag icon is alot bigger than 64x64) I'm trying to find a contact who is in-the-know about nitty-gritty win32 details. > Recent versions of Render support full color cursors with an alpha > channel which it should be possible to use to these to draw many > drag icons. This is great. I'll check it out. > Basically all the relevant docs are in the X distribution > > xc/doc/specs/Render > xc/lib/Xcursor/Xcursor.man Thanks! -- David Jeske (N9LCA) + http://www.chat.net/~jeske/ + firstname.lastname@example.org _______________________________________________ Forum mailing list Forum@XFree86.Org http://XFree86.Org/mailman/listinfo/forum
