- Rotation property bits. Rotate-(degrees)
the "rotate-" and "reflect-" things were supposed to be the names of the property bits. I guess some quotes around them would have been good.
In any case, I tink here we should refer to the define names. eg "DRM_ROTATE_<degrees> rotates the image by the ..."
rotates the image by the specified
- amount in degrees in counter clockwise direction. reflect-x and reflect-y
same here with "DRM_REFLECT_X and DRM_REFLECT_Y ..."
- reflects the image along the specified axis prior to rotation
