Not sure if this change is worth it. Probably slightly faster but less readable.
The transform() method has explicit code to handle 1d input, so transform_point() is redundant with transform() (... and is anyways implemented in terms of transform(), so not faster either)... and longer to type. Replace it throughout the codebase. Also compress consecutive calls to transform_point() with a single call to transform(), which may be a bit faster (one matrix multiplication instead of two); also a single replacement to use transform_bbox as appropriate. Only "deprecate" transform_point in the docs because I don't really want to discuss here whether this would be too disruptive...
