+Clients own windows
+Windows are composed of multiple regions that conform to several types (see below)
+- Re-draw is handled by using these regions
+
+Server-side rendering primitives:
+ # Apply to regions, rendered in fixed order, each has an ID
+> Auto-scaling bitmaps
+ - Control backed by an image with three/five regions per axis
+  Edge Fixed, Fill, Center Fixed, Fill, Edge Fixed
+ - Definition is via two pixel counts (edge width, fill width), rest is derived
+ - Command to switch backing image to another already provided
+> Tiling bitmaps + filled rects
+> Text (single line)
+> Canvas (Takes drawing commands, draws to internal buffer)
+> Shared buffer (of an unspecified pixel format)
