Patch from Jaggz H, thanks!
[#31096] Weight-painting: Brush-specific weights
http://projects.blender.org/tracker/?func=detail&atid=127&aid=31096&group_id=9
Each brush's weight can now be set individually, can also enable
unified setting (same as size and strength have.)
Added readfile code to the patch: subversion bumped to 1, brushes get
default weight of 0.5, unified weight enabled by default and value
from old vgroup_weight field.
Things like brush size and strength accessors now take a scene
parameter rather than guessing about which Scene's unified paint
settings to use.
Setting the size/strength through RNA can now be done separately for
the brush or the UnifiedPaintSettings.
The UI python code required updating to check whether the
size/strength controls should use brush or UnifiedPaintSettings RNA.
Radial control also required some updates to switch between the two
RNA sources.
Added RNA for the unified paint setting flags that matches the Brush
RNA. Fixed the getter/setter functions to avoid guessing which Scene's
UnifiedPaintSetting to use. The getter functions take a Scene pointer
now, the setter functions are removed in favor of a more explicit
approach through RNA:
Rather than RNA choosing whether a property's value is in the Brush or
in the UnifiedPaintSettings, there are now explicit properties for
both. The UI code has been modified accordingly to switch the toggle
buttons between affecting the Brush and the UnifiedPaintSettings.
File subversion is bumped to two in order to copy over the old fields.
This removes two RNA properties, sculpt_paint_use_unified_size and
sculpt_paint_use_unified_strength.

* this loop is called multiple times per vertex (not addressed in this commit)
* functions like brush_use_size_pressure(), brush_use_size_pressure() called unified_settings() twice when they didnt need to.
looks like this code cant work right with multiple scenes, added a comment on this - but at least avoid calling unified_settings() multiple times in single functions.
- Rotation now happens around initial stroke location rather than around scene origin
- Added slider for rotation strength which helps in cases only few rotation is needed
to be to increase the precision of such strokes
- remove unneeded type check from convert grease pencil operator.
- correct some error prints & use __func__.
- make copy_libblock take an ID* argument rather than void*.
so path manipulation functions dont run multiple times on the same path in the case of sequence strips where the one directory is used as the base for many images.
- use 'const float *' and array size in some function declarations.
- replace macros for BLI_math functions INPF, VECCOPY, VECADD etc.
- remove unused VertRen.clip struct member.
- remove static squared_dist() from 2 files, replace with BLI_math function len_squared_v3v3().
- use vertex arrays for drawing clipping background in the 3D viewport.
This fix also allows for partial update of the image, speeding up painting.
The different code path implemented will be used to upload high resolution images to OpenGL when onion branch is merged.
Due to conversion of float textures to/from sRGB, corrections made to brush color sampling to take account of the image profile. This is not 100% correct yet as texture images used for projection painting strokes are not converted to/from sRGB yet(This has been decided due to loss of precision for 8-bit formats). It will have to do for now, though.
last-minute update, exr image loading is broken, will fix asap
This was caused because a small part of sculpt's radial control code did not make it into the new version. The old code would set a new object-space size by scaling it proportional to how much the new screen-space size was changed.
The solution I implement here is to do the same scaling inside the RNA callbacks. This way, users of those properties do not have to worry about inconsistency.
I added a comment warning that brush_set_size, brush_set_unified_size, brush_unprojected_radius, and brush_set_unprojected_radius do not guarantee consistency because it is not always possible to precisely know what the new unprojected radius is in all contexts where you might set the size.
I would implement the consistency check at the lower level (in those listed functions) but at this time I think it needs to be looked at to make sure that won't cause problems. In addition, I am not sure that scaling by the ratio of change is strictly correct in all cases.
In any case, this at least fixes the immediate problem.
Patch to make the radial control more generic with RNA. Patch was
reviewed here: http://codereview.appspot.com/4280080/
Prior to this update, the radial control code in trunk had generic
parts of the radial control implemented as an incomplete operator
within WM. Then each different user of the radial control had to
implement a separate operator to actually pass in specific brush data
-- e.g. sculpt's brush size, vpaint's brush size, etc.
This patch removes all the extra operators and makes the WM operator
do everything. It now takes several RNA path strings as its properties
-- the only required property is data_path, which specifies the data
to be modified by the radial control. The other paths affect display
in various ways, e.g. rotation, color, etc.
In addition to decreasing some duplicate paint brush code, these
updates make it pretty easy to enable radial control for other
purposes (and it can be set up entirely though python or keymaps, no
extra C code needed.)
- making local object data - Curve/Mesh/MBall lost references to linked materials.
- joining a linked mesh object into a local one lost the link.
As well as these reported bugs, checked all local functions for consistency/correctness and found other cases which would also fail.
- making local metaball didn't ensure unique ID name.
- make_local_armature() was missing check for object users - main body of code would never run.
- local particles didn't set the dupli-group or textures to extern.
checked all local functions for consistency/correctness.
big spacing. Not sure if it's the best solution or it should be fixed when
calculating new areas.
It'll be cool if somebody else familiar with this area will check this.
- Added option "Fixed Texture" to the UI. Because of strange reason,
this feature was implemented but hidden from users.
Would be cool, if somebody familiar with 2d texture paiting check.
- Fixed some issues in existing code of fixed texture paiting.
It now handles brush radius and curve correct.
- Also fixed issue with paiting with texture from node tree - it used
to be painted with regular brush color instead of texture.
- rename rna collection structs Main prefix to BlendData: eg, MainObjects --> BlendDataObjects
- printing python collection now prints its type (when available)
- renamed shadowed vars in bpy_rna.c.
- when making functions static I also made debugging/test functions static, reverse and add definitions to headers instead.
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.
Manually disable jitter usage for anchored and drag dot brush stroke metdhods.
Jitter slider is hidden in UI for this strokes so users can't set it to 0 by hand
and even if this slider would be visible in UI jitter gives wierd result for
this stroke methods.
