implement absolute background-placement for Windows, sort of -------------------- ChangeLog entries follow: -------------------- src/ChangeLog addition: 2010-03-12 Ben Wing <ben@xemacs.org> * redisplay-msw.c: * redisplay-msw.c (mswindows_output_dibitmap_region): * redisplay-msw.c (mswindows_output_pixmap): * redisplay-msw.c (mswindows_clear_region): Have a crack at implementing the `absolute' property for background pixmaps. It seems to work; however, things don't work quite right in relation to window sizing/moving. In particular, ideally when you move the window the background should stay in place but it doesn't; instead it moves, and when you hit C-l it gets redrawn in the "proper" place. When resizing you get some serious jitter, apparently as first the image gets moved then redrawn in the correct offset position. #### Not sure how to fix this.
