graphics/nxbe/nxbe_bitmap.c: Fix another coordinate system problem.
graphics/: Review use of device coordinate system with window frambebuffer and make fixes accordingly.
graphics/nxbe/nxbe_fill.c: Fix a coordinate system bug. Was trying to update the window fraembuffer using the device coordinate system. Need to use the relative coordinate system.
graphics/: Use DEBUGASSERT instead of return an error since the is no user to handle the errors within the NX server. Use CONFIG_DEBUG_GRAPHICS instead of CONFIG_DEBUG_FEATURES in most cases.
graphics/: Nothing under graphics/ should set the errno.
Squashed commit of the following:
Update TODO list
graphics/nxbe: The moverectangle renderer now supports updates to the per-window framebuffer (unclipped) as well as the graphics device memory (clipped).
graphics/nxbe: The filltrapezond renderer now supports updates to the per-window framebuffer (unclipped) as well as the graphics device memory (clipped).
graphics/nxbe: The getrectangle method now returns data from the per-window framebuffer if available.
graphics/nxbe: The fillrectangle renderer now supports updates to the per-window framebuffer (unclipped) as well as the graphics device memory (clipped).
graphics/nxmu: If a window supports a per-window framebuffer, then redraw callbacks are suppressed and the device content is updated from the shadow, per-window framebuffer. graphics/nxbe: The copyrectangle renderer now supports updates to the per-window framebuffer (unclipped) as well as the graphics device memory (clipped).
graphics/nxbe/nxbe_setsize.c: Reallocate the per-window framebuffer when the window size changes.
- Logic that generates the low lever framebuffer renderers for the per-window framebuffers,
- The logic that picks off the per-window framebuffer updates from normal graphics device updates. This logic must update both the per-window framebuffer and the graphics device (from the framebuffer).
Squashed commit of the following:
graphics: Add logic to allocate the per-window framebuffer.
graphics: A few fragmentary thoughts on how a per-window framebuffer could be represented and allocated.
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.
Squashed commit of the following:
graphics/: Rename nxfe_reportposition to nxmu_reportposition. The is no longer an nxfe layer.
graphics/: Renmae nxfe_redrawreq to nxmu_redrawreq. The is no longer an nxfe layer.
graphics/nxmu/nxmu.h: Renmae nxfe.h to nxmu.h. There is no long an nxfe layer.
graphics/: Rename nxfe_state_s to nxmu_state_s. There is no longer an nxfe layer.
graphics/: Rename nxfe_conn_s to nxmu_conn_s. There is no longer an nxfe layer.
