This way we'll be sure (in debug builds) that regular BVH traversal is not used
for QBVH tree (could happen because of mismatch of logic in kernel and render).
The reason for this is that we don't sue SSE optimization for 32bit platforms
because of T36316.
Things to look into:
- Nail the root of the issue of that report
- Implement non-SSE traversal code for QBVH

The layers list and the Dopesheet channels now show color swatches for both the
stroke and fill colours now. This is useful when you've got layers that only
use either/or.
* Currently, these only get shown if the relevant opacity setting is high enough
for that aspect to contribute to the result.
* The sizing of these items could do with some more tweaking (especially in the
Dopesheet), as these may now be too small to accurately see and/or interact with.
* There are some potential issues when using near-gray (or actually, colours similar
to the list backgrounds, but that issue exists in other areas of Blender anyway.
(NOTE: At this stage, these changes are still experimental, and not for 2.73 yet)
Since I don't have a (pressure sensitive) tablet handy, I can't really test this
out, but apparently there is a bug which currently exists with the following description:
"Small Dots, when you do just one click a single GP dot is created, it´s fine but don't recognize the pen pressure, always the maximum value of thickness, and
It´s so easy create dots accidentally (even when you use the eraser, this dots appear spontaneously) and you start to have big screen-size-constant dots beside of you fine lines."
This commit just shuffles around the order of things a bit so that some of the misfiring
events might get skipped instead.
This commit includes a few things:
* It moves the Rake and Random flags from the brush to the MTex.
* The first change allows mask textures to have independent rake
support.
* Random rotation now has an angle value that controls the width of the
effect from the rake or default angle
* Rake and Random are now supported together.
Initially it was moved to allow setting keymaps of python defined menus
in C but looks like it breaks macro definition in python.
Thanks to Julian for tracking this down. It should fix T42485
Safe for 2.73...
This revert rB9b0ab890676790bb1e8e77797629b889ea66f69e - needed to set that threshold to a small
negative value to remove the last artefacts reported in T39735, but now I could not reproduce
any with the previous 0.0f value, so restoring it for the time being.
If this 'shadowed neighbor face' case re-appears, we can always choose a value in-between, like -1e-18f...
Seems the parent check didn't go deep enough and only checked single parent.
Now it checks the chain of parents which seems to be correct but requires
much more intense testing.
This commit implements heuristic which allows to skip nodes pushed to the stack
from intersection if distance to them is larger than the distance to the current
intersection.
This should solve speed regression which i didn't notice in the original QBVH
commit (which could have because i had WIP version of this patch applied in my
local branch).
From quick tests speed seems to be much closer to what is was with regular BVH.
There's still some possible code cleanup, but they'll need a bit of assembly
code check and now i want to make it so artists can happily use Cycles over the
holidays.
This is rather a handbook example how NOT to do things in SCons, ideally
it should be official SCons target so all the dependencies and source file
modification stops being our worry. Especially since for CMake we already
do have an app to do generate all the data.
I don't have time to clean this up now but this constant icons regeneration
just pisses me off atm.
Currently, code just checks whether a text-edited button uses a given icon (VIEWZOOM) to decide to apply changes on each typed char.
This patch adds a propper button flag (UI_BUT_TEXTEDIT_UPDATE) and a dedicated RNA flag (PROP_TEXTEDIT_UPDATE) for that.
It's also now usable not only for text buttons, but also for example for num buttons when in 'text edit' mode, etc.
It also fixes an actual bug, which is for text properties, in 'immediate' mode, hitting escape would not restore org value, because `ui_apply_but_TEX()` would set its orgstr to NULL on first call (giving it to `but->rename_orig` instead of copying it).
Note no change in behavior is expected from user POV.
Update for addons using that 'VIEWZOOM' icon 'feature' will follow (if any).

basically shadow rays were totally broken and most of the time did not record
any intersections, leading to really ad rendering artifacts.
This commit makes it so regardless of enabled optimization level render result
would be the same.
This issue doesn't happen with 6.5.12 and there's slight piece of hope it'll be
fixed in next toolkit releases..
For now we're forcing CUDA to not inline ray precalculation. This could lead to
some speed regression, but wouldn't expect it to be huge -- this code does not
run that often comparing to actual triangle intersection.
We might remove this again in the future, but for testing purposes
during the release cycle, this will be useful.
The setting defaults to QBVH, and can be found in the Performance panel.
This is harmless for now because tail of the node is zero in there, but better
to fix it early so in the case of extending BVH nodes this code doesn't give
issues.
