Finally in 2.5 branch :)
Still things to do, but will continue working in here. I won't bother
repeating the commit messages from the last year or so, however I've
written up some technical docs to help Ton/Brecht/etc review and find
their way around the code:
http://wiki.blender.org/index.php/User:Broken/VolumeRenderingDev
That above page has some known issues and todos listed, but I'm still
interested in bug reports.
Credits for this code:
* Matt Ebb
(with thanks to Red Cartel/ProMotion Studios)
* Raul Fernandez Hernandez (Farsthary) for patches:
o Light cache based multiple scattering approximation
o Initial voxeldata texture code
o Depth Cutoff threshold
* Andre Susano Pinto for BVH range lookup addition
* Trilinear interpolation adapted from pbrt
* Tricubic interpolation from libtricubic
Made toggle buttons less wide, with less extra space around them
Made number widgets wider to allow larger numbers, such as the current frame field in the timeline.
Patch by Lorenzo Pierfederici (lento). Many thanks!
* Ported some more menus to python (Pose, Particle...)
* Some cleanup and reorganization in the python file to reduce code. :)
* Cleanup of old C buttons code.
This solves one of the last remaining hurdles for
volume rendering. Previously it always used ray
tracing to shade other objects inside or behind the
volume. This meant that said objects would look
aliased, unless you used Full OSA on the volume
(which is slow!). As well as this, it meant that you didn't
get a good alpha channel out of the volume to use for
compositing, similar to ray refracting materials.
This commit enables z transparency for volume
materials. Although it can be potentially less
physically correct, in most situations there's no
difference, and you get the benefit of nice sampling for
other objects and an alpha channel for compositing too.
-Made Mirror and Transparency panels more consistent.
-Improved greying out, and better communicated the fact that alpha settings do work even if Ztransp/Ray Transp are not enabled. The results of low alpha and no Ztransp/Ray Transp look weird though - is this supposed to be supported?
-Added Flare panel for halo.
-Improved SSS panel.

Other changes:
* uiItemR, uiItemFullR, uiItemFullO now accept a flag argument rather
than multiple different "boolean" arguments, but still exposed as
booleans to python.
* Fix RNA to support setting PROP_RNAPTR for return values.
* Alt-S in Object Mode would crash. Was caused by modal-keymaps for Pose Mode not being cleared when not in Pose Mode.
Also fixed what appears to have been a copy+paste error for Armature Sketching keymaps.
* Active KeyingSet menu in TimeLine header is now properly editable. Was using the wrong type of layout call to do this.
Made Hook Modifier be able to use bone targets. However, I haven't been able to verify that everything will work perfectly, since just creating a new Hook Modifier and assigning targets doesn't set hmd->indexar correctly.
* Popup menus now remember the last clicked item again.
* Modifier and File Format menus are now organized in multiple
columns with categories.
* Hook, explode, uv project modifiers have all their buttons
again with the relevant operators implemented.
* Modifiers that can't be added by the user, or don't work on
curves for example, are not in the menu anymore.
* Fix search menu overlapping buttons when near the bottom of
the screen.
* Fix uv layers search menu not working in some modifiers.
* Cleanup popup menu code a bit, layout engine is used in more
cases now instead of ugly position calculation code.
* Refactored weight paint to use the new stroke code, now does smooth stroke and stroke spacing.
Note: weight paint is failing to free it's MocNodes in 2.5, someone might want to look into that
* 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
* cache for low res (deactivating high res for now)
* new way of view3d rendering of smoke (no longer 3 axes) -using 3dtexture now (introduced into gpu/intern)
* introducing LZO and LZMA libs into extern (makefiles missing for now)
* reducing memory usage after simulating for the frame ended (freeing temporary buffers)
* splitting smoke into 2 modifier for the cache-sake (it cannot handle more than 1 cache on the same modifier-index)
* no color on gui anymore
* fixing non-power-of-2 resolutions (hopefully)
* fixing select-deselect of domain drawing bug
* fixing drawobject.c coding style (making Ton happy) ;-)
HINT #1: If scons doesn't work -> cmakefiles are up-to-date, couldn't test scons (but i tried to mantain them, too)
CODERS HINT #1: we really need a way to disable adding all modifiers through "Add Modifiers" dropdown!
WARNING #1: before applying this commit, deactivate your SMOKE DOMAIN in your old files and save them then. You can open them then savely after that.
WARNING #2: File and cache format of smoke can be changed, this is not final!
Implementation:
* NC_SCENE or NC_OBJECT cause scene->stats to be cleared.
* NC_INFO is sent to tag info headers for redraw.
* In UI scene.statistics() creates scene->stats if it is
NULLd, and then returns the string.
* Fix header menu spacing bug, and make it consistent for all headers.
* For consistency, always put menus first in the header, then any enums
to switch the type of data displayed.
* Node editor header ported to python layout. Still quite a few
operators missing to make the menus complete.
* RNA wrapped node editor, and added use_nodes property to material
and scene.
* Added Shading and Performance panels in the scene buttons,
containing the options previously in the 2.4x game menu.
* Added show framerate/debug/physics/warnings back in game menu.
* Moved these settings from G.fileflags to scene GameData.
* Enabled Display Lists by default.
* Some other small game scene button tweaks.
* Added UI for brush stroke. Contains for now spacing and smooth stroke
* Removed Sculpt UI for airbrush -- doesn't do anything in sculpt mode
* Improved smooth stroke by using float instead of int precision, so smooth stroke is even smoother now
* Exposed Tex.use_nodes, Tex.nodetree, MTex.which_output in RNA
* Added node controls to texture buttons (Use Nodes and Use Output)
* Made new texture outputs have unique names by default, though unique names still aren't required.
Note: The preview window in the texture buttons only takes which_output into account when in "material" mode, and in the material half of "both" mode; the plain texture display ignores the user's output choice.
This is because ED_preview_draw draws a Tex* and not an MTex* -- still some work to do here.
