The assumptions made when getting the size of the window for the
paint volume turned out not to be accurate in all cases -
get_paint_volume() could be called on windows without computed
bounds.

+New Features in Theme Format Version 3.1
+========================================
+
+Additional predefined variables are added for positioning expressions:
+
+ frame_x_center: the X center of the entire frame, with respect to the
+     piece currently being drawn.
+ frame_y_center: the Y center of the entire frame, with respect to the
+     piece currently being drawn.
+
+The <title/> element now supports an "ellipsize_width" attribute. When
+specified, this gives a width at which to ellipsize the title. If not
+specified, the title will simply be clipped to the title area.
+
+New Features in Theme Format Version 3
+======================================
+
+Format version 3 has exactly one new feature; any element in the file
+can now have a version attribute:
+
+  version="[<|<=|=>|>] MAJOR.MINOR"
+
+(< and > should be to be entity escaped as &lt; and &gt;). If this
+version check is not met, then the element and its children will be
+ignored. This allows having alternate sections of the theme file for
+older and newer version of the Metacity theme format.
+
+When placed on the toplevel <metacity_theme> element, an unsatisfied
+version check will not just cause the contents of the file to be
+ignored, it will also cause the lookup of a theme file to proceed on
+and look for an older format 2 or format 1 file. This allows making a
+metacity-theme-3.xml file that is only used the format version 3.2 or
+newer is supported, and using metacity-theme-1.xml for older window
+managers.
