+Server-side rendering primitives:

+> 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)
