Basically, blender adds a few metadata fields to images when
we render an image. Those metadata can now be viewed in the
image editor.
Also, made sure metadata are available when we write imbufs
to disc with "Save As". There may be more cases here that need
fixing, but this means that loading an image with metadata
will now properly preserve them in blender.
Generalize logic for vert/edge/face selection:
- index cycling.
- selection bias with mixed modes.
Details:
- Edges now support index cycling (as verts/faces did already)
- Cycling over near elements is now only enabled when the mouse position remains the same.
- No longer do 2 selection passes to perform index cycling.
Fixes:
- Edges behind the view could be selected (surprising nobody reported!)
- Selection bias now only changes the element that gets picked without interning the return distance
(was buggy with mixed modes).
In addition to the unlink icon to clear a value,
When cleared, show an eyedropper to select objects or object-data
(was already available via the EKey).
When mixing vert/edge/face with select-visible,
face selection could fail when not close enough to the center.
This also fixes a bug where the bias for verts over edges would
prefer faces over edges too, making edges harder to pick.
Mixing edge with other selection modes works more predictably now.
- distance from edge check wasn't clamping 0-1
- vertex bias wasn't taking pixelsize into account.
- index & pass counter were floats
Also some improvements
- use BMesh lookup tables when available.
- use structs to avoid issues getting out of sync.
This way we can get rid of inefficient memory usage caused by BVH boundbox
part being unused by leaf nodes but still being allocated for them. Doing
such split allows to save 6 of float4 values for QBVH per leaf node and 3
of float4 values for regular BVH per leaf node.
This translates into following memory save using 01.01.01.G rendered
without hair:
Device memory size Device memory peak Global memory peak
Before the patch: 4957 5051 7668
With the patch: 4467 4562 7332
The measurements are done against current master. Still need to run speed tests
and it's hard to predict if it's faster or not: on the one hand leaf nodes are
now much more coherent in cache, on the other hand they're not so much coherent
with regular nodes anymore.

This way memory overhead caused by the BVH building is not so visible and peak
memory usage will be reduced.
Implementing this idea is not so straightforward actually, because we need to
synchronize images used for true displacement before meshes. Detecting whether
image is used for true displacement is not so striaghtforward, so for now all
all displacement types will synchronize images used for them.
Such change brings memory usage from 4.1G to 4.0G with the 01_01_01_D scene
from gooseberry. With 01_01_01_G scene it's 7.6G vs. 6.8G (before and after
the patch).

copy.
What happens is that the strip is copied, but it still refers to the old
scene. Here we need to fix this by referring to the copy of the strip
and also do it after copying to make it order independent.
Following the initial action management commits for 2.74, blurrymind pointed out a
problematic workflow involving the "Browse Action" dropdown in the Action Editor
which would lead to actions being accidentally lost. Namely, it turns out that
game animators frequently flip between different actions from the Browse menu while
working.
While the new up/down operators and/or other NLA based tools are better suited to this
without the problems of actions getting lost, some additional precautions were needed
for the Browse menu as well. So now, if the active action will have no users as a result
of the switch (i.e. it was a new action, and the user is checking on a previous action
via the Browse menu), this action will now get stashed. This workflow is not perfect though,
as there is the problem of the stashed action strips not reflecting the actions they reference.
When a NLA strip is being tweaked, it should not be possible to use the Action Editor to change
the action that it uses. Instead of changing the action in tweakmode, it now exits tweakmode
first before doing so.
As reported by zeffi, the "show_points" option was not working in master.
It probably broke recently, after some changes meant that the point sizes
weren't geting set prior to drawing these points anymore. Since this was
originally added as a debugging tool (though it is now somewhat redundant
due to the stroke editing functionality, which uses/exposes the same points),
this option wasn't really that important. I have decided to add back a toggle
for this to the UI though, since it can be used for some interesting effects...
A new function (RunPythonCallBackList) to call all python functions
contained in a python list was developed.
This function has:
- first argument is the python list of callbacks
- second argument is a python list of arguments
- third argument is the minimum quantity of arguments
- forth argument is the maximum quantity of arguments
It improves flexibility and supports *args.

Rename calc_flatten_center to calc_area_center,
since theres no 'flatten' spesific logic there.
Also refactor calc_area_center, calc_area_normal, calc_area_normal_and_center
so they're next to eachother - they're almost the same,
having them scattered about isn't helpful.
