loading the backends was handled in a really silly way. for instance, I have all the backend installed and in the previous version _all_ these backend would get loaded! serious overhead... so, pythonocc is now more selective about loading the backend and does so in a logical order.

fixed the menu bar issue, and added a method that centers the window and sizes the window, depending on the resolution of the screen ( i got a retina screen ;) )
the latest version of KBE…
updated Utils... need that for some cool changes to the OCCViewer...
pretty cool changes to the viewer 1) support for displaying vector 2) heavily optimized DisplayShape version when multiple TopoDS_Shapes instances are given for display. Using the power of the AIS_MultipleConnectedInteractive class, a 10 fold speed increase can be achieved, since the visualization attributes than become shared. think of it as a vectorized version of DisplayShape... 3) ShiftSelect was implemented, such that multiple entities can be selected 4) finally _very_ important is that DisplayShape uses the update=False attr as standard. I probably need to fix this in the examples, but it is _super_ irritating if update=True is the default, since your code will be laudered with update=False statements... it gets _really_ ugly that way... so this is the sane default....
mehhh small merging issue ;(
something very creepy and Heisenbergian is going on... looks like the IDE is reverting changes I just made... really scary...
i really am not very good at merging... sigh... what is really worrying me though that the earlier parameters in animation.py are really ORDERS OF MAGNITUDE from something that works well on my computer lets _please_ compare our different timings, it looks like this is indicating a serious regression...
on my machine it takes: 200 rotations took 3.33342504501
200 rotations took 3.34982919693 which _really_ are absurdly low values.... lets looks into that! this is pretty worrying...
fixed a OSX specific approach to loading the webgl scene in the browser, now using a python stdlib module, webbrowser
minor changes to DYN
checking the examples, making minor fixes, those related to DisplayShape and SimpleGui basically
the topology module got a lot of love and is now compatible with KBE, such that KBE types are returned. also, its now possible to ignore the direction of the edges for example, which is very practical
promoted Qt to use an opengl widget
more smaller fixes, while testing and checking all examples
small additions to DYN
interactive feauture tree should make the distinction between qt and wx
deleting display examples that are no longer supported
updated and polished the traits viewer to the current version of traits, 4.3
