fixing [#11362] Blender.Draw.Image() method does not clip properly
also return silently on zero zoomlevel rather then raising an error, only raise an error on negative values.

[#12106] Memory leak in sequencer (>10MB/frame)
in parts: inner contents of meta strips are freed up after calculation
making more room for the cache.
Actually have to think of a mechanism, that remembers, which output
frames are asked for and caches only those.
I'll work on making it more generic.
So far it querys faster than kdtree, but building the tree is slower.
And bvhtree NN uses an heuristic based on the last match.
Shrinkwrap (OBCube)24578 over (OBSuzanne)31658
kdtree
build: 30.000000ms
query: 1360.000000ms
bvhtree
build: 140.000000ms
query: 490.000000ms
Shrinkwrap now uses bvhtree (binary tree, 6dop) for nearest vertex.
The best rules for stereo rendering are now applied to Blender. Here is the new situation:
1) The focal distance is now settable through the GUI: select the camera (each camera can have a different setting) and go to the camera data (F9): the "Dof Dist" and "Dof Ob" can be used to set the focal distance for that camera. The "Dof Ob" is interesting because it sets the focal distance so that the center this object will appear at the surface of the screen when running the game.
2) The eye separation is automatically set to focal_distance/30, which is considered to be a reasonable value. If you need a different value, you can always use Python scripting.
Notes:
- If you switch camera during the game, the focal distance will also change unless you have set the focal distance by scripting, in which case it overwrites the focal distance setting of all cameras.
- If you don't set the focal distance in the camera data or by scripting, the default value will be used. The default value corresponds more of less to the near clipping plane which means that all the objects will be very far with little 3D effect.
- If you don't set the eye separation by scripting, it is automatically computed as focal_distance/30, regardless on how the focal distance was set.
Transform conversion was resetting constraints when used to calculate orbit center.
This is a tentative fix, it fixes this particular case but maybe not all.
Added proper gear support and fixed some misc errors in the setup of this transformation (negative values hav no effect, so use absolute value and other small things like that)
This fixes:
[#11745] Blender crashes when changing Scenes on Sequencer`s Strips
containing:
- last_seq was set to null by scene-render
- button handling wasn't very robust (didn't check for null)
- REDRAWBUTSSCENE was missing
the problem was that the buttons would use the first nurb if there was no 'lastnu', but the makeknots function only checked for lastnu. this meant the knots would not get re-allocated on
values would be written outside the array.
