* when check_valid_nurb_u/v fails, no curve is allocated or drawn.
* knotsu/v could be NULL but some functions didn't check for this, make sure this is checked for everywhere.
* The interface didnt change check the order when the bezier u/v flag was set, added functions clamp_nurb_order_u/v that takes into accound the number of points and the bezier u/v flag.
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.
added checks for a nurbes orderu being larger then pntsu.
This has the same effect as the curve having only 1 point. (its display list is not generated
but it is still added but a dummy displist with zero points is made)
memcpy was also being used where the memory overlaped (probably worked in most cases but this is incorrect and valgrind complained), use memmove
instead.
- "Memoryblock free: attempt to free NULL pointer" messages related to the Material node (Add->Input->Material). Deleting it and quitting Blender would bring 2 or 3 of these warnings. Trivial fix (check if NULL) in blenkernel/intern/node.c, though Nodes devs may be interested. Found while testing to fix the following bug:

- Bug #11715 reported by Alexanter Feterman:
http://projects.blender.org/tracker/?func=detail&atid=125&aid=11715&group_id=9
Adding a Dynamic node and setting it to a pynode script would crash Blender if no Material Node (MatNode) was present.
Thanks Alexander for reporting and Brecht for assigning it to me.
Added (disabled) MKV support. Might come handy later, if someone finds
out, why it instantly crashes after 2 frames.
Made it impossible to set min_rate higher than max_rate in render buttons
panel.
* option to export modifier applied objects
* option to export quads as tri's
* added back compress option (will default to enabled if you use .x3dz as the extension)
* NLA scaling was being incorrectly handled with fractional values. This was caused by clamping to integers instead of floats when making sure the scale value was positive.
* Added checks to help prevent some weird cases that may sometimes occur and cause problems
removed frame numbering from BLI_convertstringcode into its own function (BLI_convertstringframe), many uses of BLI_convertstringcode were passing dummy frames values anyway.
in cases where adding the current frame number to a filename is needed run BLI_convertstringframe(...) after BLI_convertstringcode(...)
There are some cases Im not sure BLI_convertstringframe is needed, these have been commented as todo, but at least have the same functionality they used to.
from center of every metalement to 26 directions and try to find every place, where implicite function
crosses zero value. Size of step is size of polygonization cube. It can be proofed, that smaller size of step
is useless.
Bug #10104 reported by bebraw: missing check for how many node sockets were being created by a pynode script. Too many (more than MAX_SOCKET == 64) would crash Blender.
http://projects.blender.org/tracker/?func=detail&atid=125&aid=10104&group_id=9
Notes: moved the MAX_SOCKET define from node.c to BKE_node.h so I could use it in Node.c. Also improved error reporting in pynodes when errors occur in the init stage.
Thanks Juho (bebraw), Tom (assigned the bug to me) and Brecht (mentioned the MAX_SOCKET define).
Intel Xeon only), doing a lot of mutex locking is really slow. Getting
the image buffer for each texture read then made using more threads
actually slow down the render. Now I've split up the function in two
parts, one parts that checks if the image is available, and another
that does a mutex lock and loading if needed.
Changes quite a lot of code, so hopefully doesn't break stuff, but it
seemed to survive test with rendering a number of frames using all
image types and many threads, though this kind of threading problem
only happens once in a while .. so hard to test for.
* in scene.c in blenkernel, set_last_seq (defined in src - editseq.c) is called... this may/may not need some stubs for game-engine stuff
* removed unused vars due to old particle-effects stuff
* BPath sequencer strip looper was only operating on the active scene, now look through all scenes.
* The active sequence strip wasnt being reset when scenes switched, so you could see the previous scenes strip when switching to a new scene.
