Removal of old transform() <sob> part one.

Removal of old transform() <sob> part one.

- added in new transform the (not so useful but yah) old feature that
  does scrollwheel zoom during transform
- had to change transform call arguments for uv-window/sequence/oops to
  match new transform for mouse callback

TODO (for martin?)

- pulldown menu support to call with local axes compliant as for pressing
  it with hotkey
- mirrormenu() still uses old transform stuff...
