* 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.
