- Many X applications that have a zooming
- or "rubber-banding" feature programmed
- for MotionNotify events rely on a GC
- whose GCFunction bit is set to GXxor.
- This provides a convenient way to draw
- rectangles non-destructively. It would
- be nice if canvas-rectangles used a GC
- whose GCFunction bit was configurable.
- I suppose the same suggestion could
- be helpful for canvas-lines, too.
