View3D has been split now in a local part (RegionView3D) and a per-area part (old View3D). Currently local is: - view transform - camera zoom/offset - gpencil (todo) - custom clipping planes Rest is in Area still, like active camera, draw type, layers, localview, custom centers, around-settings, transform widget, gridlines, and so on (mostly stuff as available in header). To see it work; also added new feature for region split, press SHIFT+ALT+CTRL+S for four-split. The idea is to make a preset 4-split, configured to stick to top/right/front views for three views. Another cool idea to explore is to then box-clip all drawing based on these 3 views. Note about the code: - currently view3d still stores some depricated settings, to convert from older files. Not all settings are copied over though, like custom clip planes or the 'lock view to object'. - since some view3d ops are now on area level, the operators for it should keep track of that. Bugfix in transform: quat initialize in operator-invoke missed one zero. Als brought back GE to compile for missing Ipos and channels.
