Just makes progressive refine :)
This means the whole image would be refined gradually using as much
threads as it's set in performance settings. Having enough tiles is
required to have this option working as it's expected.
Technically it's implemented by repeatedly computing next sample for
all the tiles before switching to next sample.
This works around 7-12% slower than regular tile-based rendering, so
use this option only if you really need it.
This commit also fixes progressive update of image when Save Buffers
option is enabled.
And one more thing this commit fixes is handling display buffer with
Save Buffers option enabled. If this option is enabled image buffer
wouldn't have neither byte nor float buffer until image is fully
rendered which could backfire in missing image while rendering in
cases color management cache became full.
This issue solved by allocating byte buffer for image buffer from
tile update callback.
Patch was reviewed by Brecht. He also made some minor edits to
original version to patch. Thanks, man!
This operator (Ctrl-F) allows you to flip the lattice coordinates without
inverting the normals of meshes deformed by the lattice (or the lattice's
deformation space for that matter). Unlike the traditional mirror tool, this
tool is aware of the fact that the vertex order for lattice control points
matters, and that simply mirroring the coordinates will only cause the lattice
to have an inverted deform along a particular axis (i.e. it will be scaling by a
negative scaling factor along that axis).
The problems (as I discovered the other day) with having such an inverted
deformation space are that:
- the normals of meshes/objects inside that will be incorrect/flipped (and will
disappear in GLSL shading mode for instance)
- transforming objects deformed by the lattices will become really tricky and
counter-intuitive (e.g. rotate in opposite direction by asymmetric amounts to
get desired result)
- it is not always immediately obvious that problems have occurred
Specific use cases this operator is meant to solve:
1) You've created a lattice-based deformer for one cartoonish eye. Now you want
to make the second eye, but want to save some time crafting that basic shape
again but mirrored.
2) You've got an even more finely crafted setup for stretchy-rigs, and now need
to apply it to other parts of the rig.
Notes:
* I've implemented a separate operator for this vs extending/patching mirror
transform tool as it's easier to implement this way, but also because there are
still some cases where the old mirroring seems valid (i.e. you explicitly want
these sort of distortion effects).
* Currently this doesn't take selections into account, as it doesn't seem useful
to do so.

When adjusting settings for world textures (with Both/World preview modes),
every tweak would result in the usercount of the texture increasing. As a
result, before long the texture would claim to have over 100 users. Fortunately,
this only appeared to be just a cosmetic issue (i.e. no real memory leak here),
though it was a bit unsettling.
NOTE: this is still a bit glitchy, as now we have flickering when updating
texture settings - the texture still temporarily has a second user during
preview rendering.
The Limit Distance constraint is now allowed to use the owner/target space
settings. Previously this wasn't exposed it didn't seem sensible/useful.
However, this can be useful when dealing with dependencies between bones and the
armature gets scaled.
Usage notes:
- It is advised to select the same space for both owner and target, otherwise
the comparisons are meaningless
Each BSDF node now has a Normal input, which can be used to set a custom normal
for the BSDF, for example if you want to have only bump on one of the layers in
a multilayer material.
The Bump node can be used to generate a normal from a scalar value, the same as
what happens when you connect a scalar value to the displacement output.

It's using the Ward BSDF currently, which has some energy loss so might be a bit
dark. More/better BSDF options can be implemented later.
Patch by Mike Farnsworth, some modifications by me. Currently it's not possible yet
to set a custom tangent, that will follow as part of per-bsdf normals patch.
