CBGFX currently doesn't support portrait screens at all. This will have
to be fixed eventually but might take a bit of effort. As a first step
to make devices with a portrait panel somewhat usable, this patch will
just force a square canvas on these panels and keep the bottom part of
the screen black.
Also switch set_pixel to calculate framebuffer position via
bytes_per_line instead of x_resolution. This is supposed to be the
canonical way to do that and may differ in cases where the display
controller requires a certain alignment from framebuffer lines.
