Bring back shading in texture painting.
This works now but it uses 3 texture units instead of two. Most GPUs of
DirectX 8 (OpenGL 1.4 should cover that) functionality even should have
those, but some old GPUs might not work with that. In any case, I hope
we will be moving to OpenGL 2.1 requirement soon anyway where 4-8
texture units are usually the norm.
The problem addressed here is that there was no mean to check if an iterator
points the last of the elements being iterated over. Such checking is necessary
to reliably dereference the iterator (i.e., calling the operator*() method of the
underlying C++ iterator object).
Now Interface0DIterator and StrokeVertexIterator have an .at_last property
to check if an iterator points the last element. Using this new API feature,
the present commit partly reverts the previous commit rBeb8964fb7f19 to
better address T41464.

- Drawing grease pencil fail without scene-lock.
- Converting to curve failed without scene-lock.
- Outliner drag into viewport failed with local-view.
Few things:
- reflect() takes arguments in this order: N, I, it was swapped
in the previous code for some reason.
- Normal and view vectors are to be normalized. For the view
vector we're now using shade_view() in order to deal with the
ortho camera. However, Cycles does not support ortho camera
for reflection, but this is easy to do in a separate commit.
- Reflection vector is to be in the world space. Kudos to
Antony Riakiotakis for figuring this out!
- ignore hidden faces & verts
- when cutting a pair, select edges co-linear to the cut.
Also support creating a buffer from hidden elem's even if BMO_FLAG_RESPECT_HIDE is enabled.
(if the hflag used includes BM_ELEM_HIDDEN).
as keyboard ones!!!
Note: better solution would be to move those 'internal' events to the 0x5xxx area,
but need to talk with the team to be sure this won't break something first.
Issue here is that indices of edges will be incorrect when index of
vertices forming the edge is 3-0 or 2-0.
There are still issues here at uv edges where seam polygons intersect
each other but to solve that we need a better pass that detects uv edges
and pushes polygons along the "normal" of the edge instead of scaling
the polygon itself.
This was a little difficult to track down, basically it was a missing
escape sequence that only manifested itself when GPU did not support
bicubic filtering.
Extra:
* Fix memory leaks when an error occurs in shader compilation
* Display full shader when a compilation error occurs. Makes it easier
to diagnose if problem is caused by a syntax or compatibility error.
Include explicit control for texturing:
This commit introduces a painting mode option, available in
the slots panel. The default value "Material" will create slots from the
blender material, same as just merged from the paint branch.
The new option "Image", will use an explicit image field that artists can use
to select the image to paint on. This will should allow painting regardless
of the renderer used or for use in modifiers.
The issue was caused by the changed defaults from the Cycles side.
Because of those properties being saved as an IDProp and not being
saved to the file, every change to the defaults would ruin someone's
day updating the values.
Added a bpy.app.handler.version_update which is run after the regular
do_versions() are done and could be sued by the scripts to apply
versioning code on their settings.

The issue was caused by the world localization setting the ID_WORLD
type update tag. Now using a function which doesn't pollute the library
and which doesn't set update flags.
Added an extra option to `insert_bezt_fcurve()`, to allow full override of existing
keyframes when pasting (in this case, we do not want to inherit handles from existing
curve!).
