Previously `PageUnit` was being ignored when applying/calculating clips. Adds a `gdip_get_page_transform` function which combines the `clip_matrix` and `PageUnit` scaling (together with its inverse in `gdip_get_inverse_page_transform`) and uses this when setting the clip region and calculating clip bounds. Also adds tests for these operations.

NOTE: This does not implement support for
PageScale; I assume this should just be a simple additional scaling step applied to the page transform but I didn't need support for this at this point.
