* gdk/win32/gdkdraw.c (gdk_draw_arc): Don't draw anything if width or height is zero. Don't print a warning if Pie or Arc fails, they always fail (?) for very narrow ellipses. * gdk/win32/gdkdraw.c (gdk_draw_pixmap): Call InvalidateRgn for the part or the destination window corresponding to source area outside of the source drawable's boundary. * gdk/win32/gdkdraw.c (gdk_draw_lines, gdk_draw_polygon): Don't do anything if less than two points. * gdk/win32/gdkselection.c (gdk_selection_owner_get): Always return NULL. Gtk cut-and-paste inside a single program works better this way. (It always gets the clipboard contents from Windows, not from its own copy, which is cleared anyway. I can't say I fully understand what happens... Emulating the X selection and property stuff is a bit of a mess.) * gdk/win32/gdkevents.c * gdk/win32/gdkproperty.c: A bít more verbose logging. * gdk/win32/gdkregion.c: Fix some memory leaks (temporary regions that never got deleted). Revamp gdk_region_shrink. * gdk/win32/gdkregion.c: Fix memory leak, delete temporary regions after use. * gtk/gtk.def: Add some missing entry points. * gtk/gtkrc.c: Strip trailing directory separator from pixmap path component.
