So now, in the new "other" tex context, you can (depending on active data) have direct access to modifiers', force's or brushes' textures...
I also refactored a bit how texture contexts are handled (once again, we had some quite similar code in both space_buttons and RNA sources). This should also solve some harmless glitches like "no texture context selected in UI" sometimes when you remove data related to current texture (see e.g. after removing the material from default cube, in startup scene).
This usage of two different systems for textures, and the handling of switches between them, has been a bit tricky to get working right, but it is OK now I think. I also had to add a bool flag to buttons space, SB_TEX_USER_LIMITED (use_limited_texture_context in RNA), which indicates "new shading" texture code whether it has to ignore materials, lamps etc. (BI) or not (Cycles).
Btw, pinned textures from modifiers/force/etc. were also broken (showing nothing), now it should work too.
Thanks to Brecht for reviewing.
Fixed by adding a "texture_user_property" member to spacebuts' context, and using it to get the prop identifier in ui script.
Thanks to Brecht for its advice!
* Fix precision overflow issue with overlay previews,
* Expose alpha mask mapping to UI (still not functional but coming soon).
* More overlay refactoring:
Overlay now does minimal checking for texture refresh.
Instead, we now have invalidation flags to set an aspect of the brush
overlay as invalid. This is necessary because this way we will be able to
separate and preview different brush attributes on the overlays, using
different textures:
These attributes/aspects are:
Primary texture (main texture for sculpt, vertex, imapaint)
Secondary texture (mask/alpha texture for imapaint)
Cursor texture (cursor texture. It involves brush strength and curves)
Modified the relevant RNA property update functions and C update callback
functions to call the relevant cursor invalidation functions instead
of checking every frame for multiple properties.
Properties that affect this are:
Image changes, if image is used by current brush,
Texture slot changes, similarly
Curve changes,
Object mode change invalidates the cursor
Paint tool change invalidates the cursor.
These changes give slightly more invalidation cases than simply
comparing the relevant properties each frame, but these do not occur in
performance critical moments and it's a much more elegant system than
adding more variables to check per frame each time we add something on
the system.
This commit makes a set of fixes and improvements based on the results of
Freestyle branch review by Brecht. The discussion thread is:
http://lists.blender.org/pipermail/bf-committers/2012-October/037927.html
* The Layers panel and Freestyle-related panels in the Render tab of the
Properties window were moved to the newly created Render Layers tab.
The idea is to separate per render layer rendering options into a distinct
Properties window tab, and use the existing Render tab to accommodate
per scene rendering options.
* The new Freestyle panel was added in the Render tab. The panel header
contains a toggle button for globally enabling Freestyle, with the aim of making
Freestyle easier to find. Those Freestyle options in the Post Processing panel
were also moved to the new panel.
* GUI code was updated so that UI controls will be greyed out (instead of
being hidden) when Freestyle is disabled. Additional UI changes were also
made to reduce space consumption.
* The list of line sets was moved from the Freestyle panel to the Freestyle:
Line Sets panel.
* Old ray-casting algorithms were removed from the UI. Now only two
algorithms (culled and non-culled cumulative visibility detection algorithms)
are available, and the selection is done by the new "Culling" toggle button
within the edge detection options.
Boid operators now retrieve the particle settings from the context directly, instead of always using the particle system (which is only needed to get to the settings anyway). When particle settings are pinned there is no particle system in the context, causing the operators to fail.
effect for a render engine using new shading nodes. In short:
* No longer uses images assigned to faces in the uv layer, rather the active
image texture node is what is edited/painted/drawn.
* Textured draw type now shows the active image texture node, with solid
lighting.
* Material draw mode shows GLSL shader of a simplified material node tree,
using solid lighting.
* Textures for modifiers, brushes, etc, are now available from a dropdown in
the texture tab in the properties editor. These do not use new shading nodes
yet.

- operator strings were doing undo pushes (in fileselector text for example), this is dumb since the operators themselves handle undo.
- interface code checks rna props are arrays rather then checking the array length.
- disable properties window pin undoing.
- sequencer refresh was calling undo, disable since this is clearnign global data not handled by undo.
- added commented out code for drawing mesh vertex index/key index, useful for debugging shapekey - hook issyes.
Improving UI visualization of using Material nodes:
- Property editor: the context top line now shows the linkage path
(in material and texture view mode)
- Activating new material node refreshes preview in property editor
when in texture mode.
This should make editing textures with node materials a bit more clear.
* Particle system's are comparable to texture slots, which can
only exist within an id block. Particle settings on the other
hand are idblocks which should be pinnable just like textures.
* When particle settings are pinned only properties that make
sense without the actual particle system are shown in the
particle panel.
* Effecting particle properties with textures was possible in 2.49,
but not in 2.5 anymore.
* Now particles have their own textures (available in texture panel
for objects with particle systems), which are totally separate from
the material textures.
* Currently a basic set of particle properties is available for
texture control. Some others could still be added, but the whole
system is not intended as an "change anything with a texture" as
this kind of functionality will be provided with node particles in
the future much better.
* Combined with the previously added "particle texture coordinates"
this new functionality also solves the problem of animating particle
properties through the particle lifetime nicely.
* Currently the textures only use the intensity of the texture in
"multiply" blending mode, so in order for the textures to effect
a particle parameter there has to be a non-zero value defined for
the parameter in the particle settings. Other blend modes can be
added later if they're considered useful enough.
* Texture context was previously determined by going to the appropriate panel, for example "world panel -> texture panel" to access world textures. Additionally there was a separate button to access brush textures.
* Now the texture context can be selected directly through an expanded icon menu, which shows the available context options.
* This context selector is now at the top of the texture panel, but this could later be perhaps integrated to the context path somehow to be more intuitive.
