Subject: provide RenderControls to all otk from the display class. initialize
 them all there. try use bitshifts instead of color tables in the
 TrueRenderControl class for finding correct rgbs. Move the
 image/pixmap/xftdraw into the surface class, and it maintains them,
 recreating them when it resizes.
