I am looking for:
- optimized algorithm for rotating 32-bit image (for use with PNG hands)
- algorithm for drawing antialiased lines
- tip if there is any better way of working with 32-bit images then separating
alpha channel, working with DDB, convert DDB to 32-bit DIB and finally add
alpha channel back (drawing to 32-bit images sets alpha to 0)
- hint how to avoid minimizing of window in WinXP, when "Show desktop" is clicked
- hint how to determine if there is running any full-screen application as screensaver, games...
