Add some new FAST_PATH flags

The flags are:

 *  AFFINE_TRANSFORM, for affine transforms

 *  Y_UNIT_ZERO, for when the 10 entry in the transformation is zero

 *  FILTER_BILINEAR, for when the image has a bilinear filter

 *  NO_NORMAL_REPEAT, for when the repeat mode is not NORMAL

 *  HAS_TRANSFORM, for when the transform is not NULL

Also add some new FAST_PATH_REPEAT_* macros. These are just shorthands
for the image not having any of the other repeat modes. For example
REPEAT_NORMAL is (NO_NONE | NO_PAD | NO_REFLECT).
