nanogui: Thread: Microwindows has portrait mode

Thanks to Martin Jolicoeur, Microwindows now will
run any framebuffer driver in portrait mode.  Using
some clever programming, Martin has added virtual
xres and yres resolutions for the upper level code,
while swapping x and y in  a single framebuffer
driver file, while running on any top of any low level
framebuffer driver, including 1, 2, 4, 8, 16
and 32bpp drivers.  In addition, Martin
has added an SA1100 LCD 4bpp display
driver.

This is a big gain for the LinuxCE devices, since
many (Everex Freestyle for starters) must run
in portrait mode for "normal" operation. I'll
post these changes in 0.87pre2 very shortly.
It's quite a kick running the portrait mode on
my standard VGA system and running all
the demos sideways!!
