To transpose a BayerFormat means to flip it over its main diagonal.
For example:
G B G R
->
R G B G
The main diagonal goes from the top left to the bottom right. This
means, that the only two orders affected by a transpose are GBRG & GRBG.
When a transpose is used in combination with horizontal and/or vertical
flips it is performed after the flips. Therefore add the functionality
by switching GBRG (index 1) with GRBG (index 2), after the flips have
been applied.
