- update displistmesh_to_mesh to free existing mesh data (including
sticky, dvert, and keys if number of verts don't match)
- changed modifier panel to not allow manual addition of hook or
softbody modifiers
- changed apply modifier to apply to existing mesh (fixes bug with
materials) and to warn about loss of tface/mcol/keys/dvert/sticky
for all modifier types
- changed modifier UI to not display disclosure triangle for virtual
modifiers
- changed softbody ui to allow enable/disable

- couldn't help myself, got distracted working on something else and
wondered what these silly data pointers in MDeformVert were for.
Turns out they aren't even need! Just taking up extra memory and
space and confusing the armature deform algorithm. Naturally I
had to clean things up. Sorry Ton.

Deform weights are still stored in a pretty expensive and unnecessary
way, probably use about twice as much memory as needed, and do
way too many memory allocs.
- moved armature_deform_verts into armature.c
- some python code accessed the MDeformWeight data pointers, but
did so in a completely wrong way, I am positive this code could
never have worked (or maybe things changed during tons refactor),
regardless it wouldn't work now... will test later.

- added recalc ob, recalc data options to ctrl-alt-shift-t timer

Two quick bugfixes, thanks slikdigit!

- armature modifier was not flagged to require original data (but it
does)
- add hook messed up the ModifierData initialization, stupid bug!

- bug fix, cage buttons weren't displayed correct with virtual modifiers

- added modifiers_getVirtualModifierList, returns pointer to first modifier
but including "virtual" modifiers (for example, an object skel-parented
to a lattice has a virtual first lattice modifier)
- removed mesh_modifier(), all functionality has been incorporated into
modifier stack (well, keys still don't exist as a modifier, but I am
not sure if they should).
- added interface option to convert a virtual modifier into a real modifier
- added option to parent to lattice object or lattice with deform
- bug fix, patch of hook indices patched all hooks (oops) not just ones
for edited mesh

NOTE: Files saved with 2.38 that include an object parented to a lattice
will not load correctly, because it will look like the object is parented
only to the object (i.e. without deform). Can be simply fixed by reparenting
or adding a lattice modifier. Older files are handled automatically.

- switch to using softbody modifier, controls enabling but does not have
variables, these are still in same place. enable button automatically
makes/enables modifier.
- changed hook to hook modifier conversion to happen on direct link,
required to make sure we don't forget to free any memory for files
saved with 2.38 that have hooks.
- update modifier interface to enforce modifiers with the require-original-
data flag to not move beyond deforming modifiers.
- enforce only one softbody modifier allowed

NOTE: Once again, no modifier stack for lattice yet means softbody for
lattice does not work atm.

New "Mirror UVs" function in faceselect mode, to complement Rotate UVs.
It mirrors the UVs or Vertex Colors of individual faces (on the red edge
of the UV face).

Patch provided by Martin Poirier, thanks!

- bug fix, hook deform could crash because old files can have hook
indices that are out of range
- bug fix, hook indicies were not corrected on exit editmode (there
probably should be a general interface for this kind of patch)

- added eModifierTypeFlag_RequiresOriginalData for modifiers that
can only follow deform (for example, they store mesh vertex
indices)
- added ModifierType.foreachObjectLink for iterating over Object
links inside modifier data (used for file load, relinking, etc)
- switched various modifiers_ functions to take object argument
instead of ListBase
- added user editable name field to modifiers
- bug fix, duplicate and make single user didn't relink object
pointers in modifier data
- added modifiers to outliner, needs icon
- added armature, hook, and softbody modifiers (softbody doesn't
do anything atm). added conversion of old hooks to modifiers.

NOTE-THE-FIRST: User name field is not initialized on loading 2.38 files
so if you have saved stuff with a cvs blender you will see blank names.

NOTE-THE-SECOND: Since modifiers aren't evaluated yet for non-Mesh
objects, hooks for lattices and curves are broken. Don't updated if
you actually, say, *use* Blender.

NOTE-THE-THIRD: Old hooks used a quirky weighting system during
deformation which can't be extended to modifiers. On the upside,
I doubt anyone relied on the old quirky system and the new system
makes much more sense. (Although the way falloff works is still
quite stupid I think).

Patch #2758 Update of image module.
New Image methods from Austin Benesh:
- getPixelI(x, y)
- getMinXY()
- setPixelF(x, y, [r, g, b, a])
- setPixelI(x, y, [r, g, b, a])
- save()

sorry for the delay.
Thanks.

ideasman fix that epydoc compile for it
.

- bug fix, face center drawing was wrong for editmesh
- added several useful utility functions to editmesh,
these can simplify/clarify a lot of mesh code, check them
out
- cleaned up EdgeSlide a bit to be clearer/shorter
o bug fix, EdgeSlide did not always cancel correctly
o bug fix, EdgeSlide did not choose initial "control" edge
correctly after calc_meshverts_ext change

Removed need for vert-xs and ys in edgeslide

- bug fix, convert modifiers should free modifiers from new object

fix for bug #2906

Was allocating array for all hidden edges, not needed, just hidden with a selected vert needed

Possible fix for bug #2906

Added some parens to change eval order

Big commit, had to rework lots of selection stuff so that things
worked properly with modifiers. Needs more testing I am sure.
No, honestly, I wasn't just cleaning for the hell of it, it
was *necessary* (I would never do such a thing). Selection should
work completely with cage options of modifiers now.

- added DerivedMesh foreach functions to iterate over mapped
verts/edges/face centers. These replaced some of the drawing
functions and are more general anyway. Special edge drawing
functions remain for performance reasons.
- removed EditFace xs, ys fields
- added general functions to iterate over screen coordinates of
mesh/curve/lattice objects
- removed all calc_*verts* functions that were used for storing
screen coordinates in objects. they were recalc'd on the fly
for most situations anyway, so now we just always do that.
calc_*verts_ext was one of those calls that did dirty things
deep down in the callstack (changing curarea and poking at
matrices)
- rewrote all vertex level selection routines (circle, lasso, bbox)
and closest vertex routines (rightmouse select) to use the new
system. This cleaned up the selection code a lot and the structure
of selection is much easier to see now. This is good for future
work on allowing modifiers to completely override the selection
system. It also points out some discrepancies in the way selection
is handled that might be nice to resolve (mesh vertex selection has
fancy stuff to try to help with selecting overlapping, but it only
works w/o bbuf select, and curves/lattices don't have at all).
- had to remove ton's code to move Manipulator to cage location, this
is not reliable (can come up with a different method if requested)
- as it happens BezTriple.s and BPoint.s are basically available to
be removed, just need to rewrite editipo code that still does
background calc of screen coordinates
- MVert.{xs,ys} are still around because they are abused in some places
for other info (not sure if this is safe actually, since they are
short's and the mvert limit went up).

And did I mention this commit is comes out to -305 lines? Well it does.

made weight paint panel full width ( still try to understand that X,Y system panels use )
replaced senseless 0 opacity with 1/8 opacity

- added VecLerpf to blenlib
- switch to using DerivedMesh.drawMappedFaceCentersEM to draw
face dots, still need to do some work so this works in all
selection modes (atm it does not work in no-zbuf mode)
