Fix for the "mangles focus window when switching workspaces
and using mouse focus" bug
* src/stack.c (meta_stack_get_default_focus_window_at_point): new
function
* src/screen.c (meta_screen_focus_mouse_window): new function
(meta_screen_focus_default_window): new function
* src/workspace.c (meta_workspace_activate): use the
new meta_screen_focus_default_window()
2003-01-17 Havoc Pennington <hp@pobox.com>
* src/window.c (meta_window_handle_mouse_grab_op_event): fix event
compression code to use GDK algorithm suggested by Owen, should be
more efficient.

/* Layers vs. stack positions
|
|
* ==========================
|
|
*
|
|
* There are two factors that determine window position.
|
|
*
|
|
* One is window->stack_position, which is a unique integer
|
|
* indicating how windows are ordered with respect to one
|
|
* another. The ordering here transcends layers; it isn't changed
|
|
* as the window is moved among layers. This allows us to move several
|
|
* windows from one layer to another, while preserving the relative
|
|
* order of the moved windows. Also, it allows us to restore
|
|
* the stacking order from a saved session.
|
|
*
|
|
* However when actually stacking windows on the screen, the
|
|
* layer overrides the stack_position; windows are first sorted
|
|
* by layer, then by stack_position within each layer.
|
|
*
|
