Updated Python Mesh API to support UV and Color layers with names.
Similar to vertex group's
renamed a function in customdata.c CustomData_free_layers -> CustomData_free_layers_active and made CustomData_free_layers accept an index, this is needed so python could free layers that arnt active.
==== Rotation Snap ====
Snap is no longer limited to Translation, it works in Rotation too.
There's some bugs left with rotation snap when using constraints, I'll be ironing that next.
==== Bug Fixes ====
* Fix manipulators to always use Grid.
* Fix initialization bug (took two transform call to do a correct snap init when changing between Grid and Snap)
Image - added img.fields, img.fields_odd, img.antialias, also updated the docs. replaced Py_BuildValue with faster list creation for getPixel functions.
Ztransp Mask issue: now I did all this work to solve the exceptions, but
forgot the most simple case: regular alpha-over :)
This solves for example AA issues in ztransp-hair over solid faces.
Now the Snap To Location (Shift S) tools for bones in pose-mode
work correctly. Previously, only one of these tools was implemented,
but it only worked in some cases.
This fixes item #4874 in Todo Tracker. Was patch #5012.
The circle drawn around the snap point is now truely constant regardless of zoom and size of the window. That size if linearly proportional to the vertex size (bigger vertex -> bigger circle).
Reason: I had to make the "BUT" type in Blender to use callbacks *after* the
uiBlock was freed, because in Blender several of these callbacks invoke
drawing, which isn't possible while a block is being evaluated.
Now uses original filename for unpacking, instead of the Blender ID name.
That latter was a nice idea, but because of its 20 char maxname limit
not working well.
Added support for multiple UVs in the render engine. This also involved
changing the way faces are stored, to allow data to be added optionally
per 256 faces, same as the existing system for vertices.
A UV layer can be specified in the Map Input panel and the Geometry node
by name. Leaving this field blank will default to the active UV layer.
Also added sharing of face selection and hiding between UV layers, and at
the same time improved syncing with editmode selection and hiding.
Still to do:
- Multi UV support for fastshade.
- Multires and NMesh preservation of multiple UV sets.
(saved files cannot read back, they crash).
The implementation of this option was plain accident that it even worked
once... you cannot use the API in blender that way.
Brought back the old "image properties" panel, which actually only showed
options for real-time textures. Available in pulldown menu as "Real-time
Properties".
This header defines function stubs for builds without OpenEXR.
A quote from openexr_multi.h:
/* ugly... but we only use it on pipeline.c, render module, now */
No longer true! Function definitions should never be in header files,
I say.
