you have 16bits for 565, so on big endian it looks like:
rrrrrggg gggbbbbb
On Little endian, it is:
gggbbbbb rrrrrggg

So the general approach is to stuff the value into a guint16 using shifts and
then TO_BE/LE to get the endianness right, kinda like this:
guint16 pixel;
pixel = (r << 11) | ((g & 0x3f) << 5) | (b & 0x1f);
pixel = GUINT16_TO_BE(pixel);
