Some applications make weird assumtions on Gtk+ that do not work anymore
with the new client-side windows support. For instance SWT/Eclipse reorders
the stacking order of the X windows directly without telling gdk this,
which breaks gdk drawing as gdk now relies on knowing the stacking order
for window clipping.
This introduces a GDK_NATIVE_WINDOWS environment variable, which if set
causes Gtk+ to always use native windows. Its more compatible with
pre-csw Gtk+ behaviour if you do weird X-specific hacks, although it does
limit the size of GdkWindows to 65535x65535.
In validate_visible_area() it was assumed that gtk_tree_path_prev()
would always return the correct path of the preceding node. This is
obviously not true. The if-clause has been removed so that we now
always use _gtk_tree_view_find_path() to get the path from the tree,
node.
GtkCellRendererAccel also needs to acquire the GTK+ grab in addition to
a GDK keyboard grab. With the GDK keyboard grab, KeyPress and
KeyRelease events are delivered as usual, although we only want to
receive them for our grab widget.
Make the tooltip code a bit more robust for a case that only occurs when
GTK+ is used from a language binding. It looks like this case appears
because the memory management / ref counting is handled differently in
some of the language bindings. Instead of asserting, we will fail
silently. Also fix a think-o in gtk_tooltip_start_delay(). Patch from
O. Andrieu.
The previous code would trigger on an unmodified 'S' key for a
'Super+S' accel. The current code avoids that at the cost of breaking
combinations like 'Mod4+Super+S' which are too exotic to worry about...
Bug 591526
Shift-click inside an existing selection reduces the selection to the
range from the insert mark to the clicked point instead of removing the
selection. This makes GtkTextView more consistent with GtkEntry.
