- /* draw source window into a bitmap as we cannot scale
- a window in contrast to a bitmap. this would actually
- work with memory dcs as well, but we'd lose the mask
- information and waste one step in this process since
- a memory already has a bitmap. all this is slightly
- inefficient as we could take an XImage directly from
- an X window, but we'd then also have to care that
- the window is not outside the screen (in which case
- we'd get a BadMatch or what not).
- Is a double XGetImage and combined XGetPixel and
- XPutPixel really faster? I'm not sure. look at wxXt
- for a different implementation of the same problem. */
