More transform widget goodies;

- added 'ghosting' for while using translate/scaling widget
- added 'pie chart' ghost to denote angle while using rotate widget
- added settings to tweak widget in User menu (InfoWindow) "View & Control"
- Size: total widget size as percentage of window size
- Handle: as percentage of widget radius
- Hotspot: for clicking handles, in pixels
- Fized Size: option to make Widget size independent of window size
Not sure if all of these are useful to keep, but makes for good testing
in this stage.

Also: made #define to use new transform to be set TRUE by default now. :)
