Circle select was missing from node editor, and C key was assigned to now defunct "show cyclic dependencies". This patch remaps the key and adds circle select operator.
Functions to check intersection between rctf/rcti and a circle were also added to rct.c for code cleanliness and consistency.
called the generic node tree update function, which is happening anyway after all relevant node operators (if it doesn't that has to be considered a bug).
It has been suggested to better use the C key for circle select, this remains to be discussed.
confusion, grid snap is now the default as it seems to be the most wanted and easy to use mode.
Absolute grid snapping happens in a somewhat generic function 'applyGridAbsolute', which could also be used for objects and other transforms later on. It is conceptually similar to the 'project' snapping
option, in that it calculates a delta vector for each element on top of the overall transform, which places each node on the grid.
Node transform now uses the top-left node corner for TransformData->loc. The transform center is still the average of node centers, so that scaling and rotation works nicely.
snapGrid*** functions have been renamed to snapGridIncrement*** to distinguish better between incremental and absolute grid snapping.
mimics the previous behavior when settings were shared by both modes (but not equivalent).
NOTE: Due to the use of additional sRGB conversion in the LGG mode the result is not entirely accurate, this should perhaps be fixed.
Settings for each mode are kept in their own color values nevertheless, this avoids potential problems with float precision.
It wasn't enabled in snapping code from the beginning it seems,
but from quick tests snapping for mballs works just fine.
Maybe we could drop out check for edit object type now?
This means that if you have WITH_BF_QUICKTIME or WITH_CODEC_QUICKTIME enabled,
it will always use QTKit.
The old backend was only used on 32 bit OS X builds, now 32 and 64 bit builds will
give consistent input/output. On Windows or Linux quicktime isn't being used.
* deselect all no longer leaves an active point
* the most recently added spline becomes the active one
* on successful duplicate/delete the active point and active spline are reset
* Remove unused UI code for Info Space items. Was lying around here for some months already.
Probably we have to re-think the whole placement of the operator history thing, but thats for later. In the current config there is no room for these buttons though.
* Remove "FCurve/Driver Version fix" from help menu, was used for RNA changes during 2.5x.
* Keep utility code in animsys_refactor.py, might still become useful according to Joshua.
