Mixdown functionality.
* Mixdown possible via libsndfile and ffmpeg!
* Fixed some ffmpeg deprecation warnings
* Mixdown UI only shows working Container, Codec and Format combinations!
* Minor bugs and warnings fixed
Diff Keymaps
User edited keymaps now no longer override the builtin keymaps entirely, but
rather save only the difference and reapply those changes. This means they can
stay better in sync when the builtin keymaps change. The diff/patch algorithm
is not perfect, but better for the common case where only a few items are changed
rather than entire keymaps The main weakness is that if a builtin keymap item
changes, user modification of that item may need to be redone in some cases.
Keymap Editor
The most noticeable change here is that there is no longer an "Edit" button for
keymaps, all are editable immediately, but a "Restore" buttons shows for keymaps
and items that have been edited. Shortcuts for addons can also be edited in the
keymap editor.
Addons
Addons now should only modify the new addon keyconfiguration, the keymap items
there will be added to the builtin ones for handling events, and not get lost
when starting new files. Example code of register/unregister:
km = wm.keyconfigs.addon.keymaps.new("3D View", space_type="VIEW_3D")
km.keymap_items.new('my.operator', 'ESC', 'PRESS')
km = wm.keyconfigs.addon.keymaps["3D View"]
km.keymap_items.remove(km.keymap_items["my.operator"])
Compatibility
The changes made are not forward compatible, i.e. if you save user preferences
with newer versions, older versions will not have key configuration changes that
were made.
* Added a new "color spread" slider for "spread" effect to adjust how much colors get mixed.
* Improved smudge behavior on "wet" paint.
* Displace can now be set "incremental". This way it's added on top of previous displace.
* Added "displace clamp" setting. You can use it to limit maximum amount of displace.
* Fix: velocity data wasn't always initialized, this could lead to no effect at all or crash.
* Fix: Vertex color rendering near zero alpha values was still incorrect.
* Object velocity can now be used to determine brush influence and color.
* Brushes can now be set to "smudge" existing paint.
* Added new operators to easily add and remove surface output mesh data layers from Dynamic Paint ui.
* Fixed drip effect algorithm to work properly on forces pointing towards surface.
* Adjusted drip effect speed.
* Drip effect can now use canvas velocity and acceleration to influence drip direction.
* Fixed texture mapping for material enabled brushes.
* "Object Center" type brushes can now use "material color" as well.
* Improved surface partitioning grid generation algorithm.
* Fixed possible invalid brush collision detection when OpenMP enabled.
* Fixed incorrect random sized particle displace/wave influence.
* Fixed "Object Center" brush color ramp falloff.
* Fixed invalid zero alpha sampling when rendering vertex colors.
* Lots of smaller tweaking.
This is for bug #28141
While not really a bug, it makes it a lot easyer to use if it
has the exension. (Isn't hidden from the user when they try to load it...)
Kent
* Minor audaspace library improvements.
* Considering location, velocity and orientation in AUD_SequencerReader and AUD_SequencerHandle.
* Bugfix: Maximum and Minimum volume weren't used before in the software device.
* Bugfix: Adding speaker objects via info space crashed.
* Listener settings now get updated in the audio system.
--it's still really simplistic (and slow!) so don't try fixing an entire mesh! xD
Also, don't use it on a mesh with a mirror modifier yet, just noticed that it does both vertices instead of one.
Minor UI text update for Vertex Masking
Implemented basic audio animation.
* AnimatableProperty: Propper cache writing and spline interpolation for reading (the solution for stair steps in audio animation)
* Animatable properties so far are: volume, pitch, panning
* Users note: Changing the pitch of a sound results in wrong seeking, due to the resulting playback length difference.
* Users note: Panning only works for mono sources, values are in the range [-2..2], this basically controls the angle of the sound, 0 is front, -1 left, 1 right and 2 and -2 are back. Typical stereo panning only supports [-1..1].
* Disabled animation of audio related ffmpeg output parameters.
* Scene Audio Panel: 3D Listener settings also for Renderer, new Volume property (animatable!), Update/Bake buttons for animation problems, moved sampling rate and channel count here
Enabled by default and also enabled for older filesm so
there should be no regressions.
In some cases it's useful to not use subdivided uvs for multires.
