+	* Source/GSTheme.m:
+	* Source/GSThemeDrawing.m:
+	* Source/GSThemePrivate.h: Add GSStringFromBezelStyle and
+	GSStringFromSegmentStyle functions which return the string name of
+	the style constant for buttons and segmented controls.
+	In -[GSThemeDrawing drawButton:view:style:state], use
+	GSStringFromBezelStyle to try to get tiles for the specified bezel
+	style, falling back to the normal NSButton tiles if the fancy tiles
+	aren't present.
