 ===

-Not that metacity is huge, but a substantial amount of code is in
-preferences handling, in static strings that aren't essential, and in
-the theme engine.
-
-You can strip about 70K from the metacity binary by compiling with 
-options such as:
-
- --disable-gconf
- --disable-sm
- --disable-verbose 
- --disable-startup-notification
-
-However the result is no good for desktop use, all prefs have to be
-hardcoded in the binary, for example. If you wanted to make a really
-small metacity, here's some additional stuff you might consider
-implementing:
- 
- - add --disable-themes, which would replace theme.c and theme-parser.c 
-   with a hardcoded implementation of the interface in theme.h, 
-   should save about 80K. This should be fairly easy.
-
- - add --disable-gtk, which would implement the interface in ui.h
-   without using GTK. This one is easier than you think because the
-   main part of the window manager doesn't use GTK directly, but is
-   still fairly hard to do.  You would probably have to give up some
-   of the features, such as window menus, as menus are pretty complex
-   to implement well.  So time may be better spent adding a GTK
-   configure script feature to build GTK with only a small core set of
-   functionality.

+/* We can only (easily) apply our logic for figuring out what a window
+ * obscures if is not transformed. This function does that check and
+ * as a side effect gets the position of the upper-left corner of the
+ * actors.
+ *
+ * (We actually could handle scaled and non-integrally positioned actors
+ * too as long as they weren't shaped - no filtering is done at the
+ * edges so a rectangle stays a rectangle. But the gain from that is
+ * small, especally since most of our windows are shaped. The simple
+ * case we handle here is the case that matters when the user is just
+ * using the desktop normally.)
+ *
+ * If we assume that the window group is untransformed (it better not
+ * be!) then we could also make this determination by checking directly
+ * if the actor itself is rotated, scaled, or at a non-integral position.
+ * However, the criterion for "close enough" in that case get trickier,
+ * since, for example, the allowed rotation depends on the size of
+ * actor. The approach we take here is to just require everything
+ * to be within 1/256th of a pixel.
