* Removed some fields from struct SculptSession:
- Fields drawobject, projverts, and previous_r were completely
unused
- Field `ob' was really unnecessary, changed sculpt functions
to pass the object rather than the SculptSession
This removal of `ob' from SculptSession should should make it a little
easier to continue generalizing paint/sculpt functionality.
There should be no visible changes from cleanup.

Used a crazyspace approach (like in edit mode), but only modifiers with
deformMatricies are allowed atm (currently shapekeys and armature modifiers only).
All the rest modifiers had an warning message that they aren't applied because
of sculpt mode. Deformation of multires is also unsupported.
With all this restictions users will always see the actual "layer" (or maybe
mesh state would be more correct word) they are sculpting on.
Internal changes:
- All modifiers could have deformMatricies callback (the same as deformMatriciesEM but
for non-edit mode usage)
- Added function to build crazyspace for sculpting (sculpt_get_deform_matrices), but it
could be generalized for usage in other painting modes (particle edit mode, i.e)
Todo:
- Implement crazyspace correction to support all kinds of deformation modifiers
- Maybe deformation of multires isn't so difficult?
- And maybe we could avoid extra bad-level-stub for ED_sculpt_modifiers_changed
without code duplicating?

- remove brush array for each Paint struct, just use a single brush pointer.
- removed rna function based template filtering.
- filter brushes using a flag on the brush and the pointer poll function.
- set the brushes using a new operator WM_OT_context_set_id().
TODO
- remake startup.blend, currently brush groupings are lost.
- rewrite WM_OT_context_set_id() to use rna introspection.

function that checks whether a brush is used by that paint struct
* Fixed an improperly initialized variable in BKE_previewing_free_id
* Added an RNA access function to get the icon associated with a value

the Basis
PBVH used the same verts array as mesh data and shape key/reference key coords
were applying on the mesh data, so on some refreshing undeformed mesh was
displayed.
Added utility functions to get vert coords from key block, apply new vert coords
on keyblock and function to apply coords on bpvh, so now pbvh uses it's ovn
vertex array and no changes are making to the mesh data.
Additional change:
Store key block name in SculptUndoNode, so now shape wouldn't be copied to
wrong keyblock on undo

Most likely will not compile for others, I'd appreciate any build errors
and missing files reports (I can never seem to get everything committed
and all the build systems working without help).
Porting over the sculpt/multires tools was a breeze,
thanks goes to brecht for a design that didn't exclude
ngons and was easy to port.
Note that I've not tested externally-backed multires
file support yet. Also, I still need to write version
patch code for some cases.
Some notes:
* Like trunk, topological changes don't update multires right,
so e.g. subdivide will duplicate multires data on the new faces,
instead of subdividing it.
* If you set the debug value (ctrl-alt-d) to 1 it'll turn on
my experiments in speeding up sculpting on higher-res multires
meshes (but note it makes partial redraw not completely accurate).
* There's a bug where you have to go through editmode to get out
of sculpt mode, not sure if I inherited or created this myself.

* Smooth: vert-face map is now only created when this tool is used, would be
best to also avoid using it here to avoid a sudden increase in memory, but
is not trivial.
* Grab: now no longer uses active verts list and loops over nodes like other
tools.
* Layer: uses original coordinates from undo now to save memory when not
using persistent layer.
* Anchored: this option works again now, though is still quite slow as it
loops over all verts/faces.
Smooth, layer tools and the anchored option could still be improved to use
less memory and/or work faster by only doing things per node.

that it is able to store changes in the mesh more compact than global undo.
It doesn't integrate well with multires yet, will tackle that when I start
looking into multires, for now still focusing on sculpt on regular meshes.
|
|
* Multires sculpting appears to work now
* PBVH gets recalculated in some cases where it shouldn't, haven't looked into this yet

branch until we merge to trunk.

* Removed the BKE_sculpt file and moved it's contents (basically just the sculpt session struct) to BKE_paint
|
|
* Weight paint and vertex paint now use the same cursor setup as sculpt
|
|
* Converted vertex paint to use the new stroke system. Now supports the same smooth stroke and stroke spacing as sculpt mode.
* Refactored the paint cursor a bit, just sculpt for now but other modes soon.
* A couple warning fixes
|
|
* Converted to use Paint struct. Now all the brush modes are done.
TODO:
* Make the UI better
|
|
* Converted vertex paint and weight paint to use the new Paint type
|
|
* Added a new Paint type in scene DNA. This is now the base struct for Sculpt.
* The Paint type contains a list of Brushes, you can add or remove these much like material and texture slots.
* Modified the UI for the new Paint type, now shows the list of brushes active for this mode
* Added a New Brush operator, shows in the UI as a list of brush tool types to add
* Made the sculpt tool property UI smaller and not expanded, expectation is that we will have a number of preset brushes that will cover the basic sculpt brush types
TODO:
* Vertex paint, weight paint, texture paint need to be converted to this system next
* Add brush presets to the default blend
|
|
* Replaced FACESEL_PAINT_TEST macro with paint_facesel_test. This removes one more thing from BKE_global, and it'll make it easier to localize.
* Fixed sculpt paint cursor sometimes not showing.
