graphics: nx_openwindow() and nxtk_openwindow() now accept an addtional 'flag' parameter. This argument is not used at present but will, eventually enable a RAM backed, per-window framebuffer.
graphics/Kconfig: Add configuration to support a rambacked framebuffer. Current marked as EXPERIMENTAL because this is a work in progress.
