Function: Rotates 1bit image in memory.
Degree can be -360, -270, -180, -90, 0, 90, 180 or 270 to rotate counter clockwise.
InputData points to an 1bit image with given width and height. InputRowBytes if defined tells how many bytes per row are used in the input image. If <= 0, we calculate it. OutputRowBytes defines row bytes for output image, which is different for 90/270 rotation.
Returns true on success or false on failure.
The function is optimized for 180 degree to be quicker if image size is multiply of 8.
For 90 and 270 degree, there is an optimization if width and height are a multiply of 8.
