but we're talking about embedded systems.  of, at least, that's
what i talk about when i talk about busybox.  16-bit colordepths
and non-standard pixel orders are fairly common, and will be, for
some time.

in fact, the code from the current bbsplash patch is obviously for
a 565 display:

+                       thispix = (((short)pix[0] << 8) & 0xf800)
+                               | (((short)pix[1] << 3) & 0x07e0)
+                               | ((short)pix[2] >> 3);
+
