A toggle for this is no longer required now that both header and background
colors are RGBA (disabling Show Header is the same setting the alpha to 0).
Thanks Brecht for reviewing!
There were a number of cases where immActivate() and immDeactivate() could
get out of sync, causing crashes due to using a freed mutex lock. Refactor
the code now to hopefully avoid this always.
Based on feedback from the 'User Feedback' devtalk forum
* More opaque panels for the viewport
* Darker state colors
* Current frame color consistency for MCE
Old behavior: tagging ID with DEG_TAG_COPY_ON_WRITE will do copy-on-write
(as requested), but will also flush changes to all operations with depends
on it. This means, for example, tagging object for copy-on-write will force
its modifier stack to be evaluated.
This was needed in the earlier days of copy-on-write when things were not
well defined and when lots of areas were not doing proper tagging.
New behavior: tagging ID with DEG_TAG_COPY_ON_WRITE will only ensure copy
of the dadatblock is up to date, without flushing updates to any dependencies.
This means following things:
- We can update parts of ID without invoking heavy computation of other
parts of same ID. For example, tagging object for COPY_ON_WRITE update
on mode change will not force modifiers stack to update.
- If some dependent datablock is dependent on pointers which are invalidated
by copy-on-write (like, evaluated mesh referencing custom data layers from
original mesh), this will either require explicit tag or explicit relation
in the dependency graph.
Currently can not find a faulty case since tagging of mesh happens with
either 0 (which means, everything) or with GEOMETRY, which also forces
all dependent modifier stacks to be re-evaluated.
This fixes missing PBVH when going into sculpt mode (sculpt mode toggle
was tagging object for COPY_ON_WRITE update, which was forcing modifier
stack to be updated, which was freeing PBVH.
Some other operations might also become faster with this change.
Instead of running code to create a keymap, store them as data.
This allows for keymaps to share content as well as running
transformations at load time.
Now we light with just a user defined HDRI by default, which is useful
for material setup and texture painting and lighting without having to
set up any scene lights.
Previously it would use the scene world without lights by default, which
in some files is just black.
