2.5
Added WM Jobs manager
- WM can manage threaded jobs for you; just provide a couple
of components to get it work:
- customdata, free callback for it
- timer step, notifier code
- start callback, update callback
- Once started, each job runs an own timer, and will for
every time step check necessary updates, or close the
job when ready.
- No drawing happens in jobs, that's for notifiers!
- Every job stores an owner pointer, and based on this owner
it will prevent multiple jobs to enter the stack.
Instead it will re-use a running job, signal it to stop
and allow caller to re-initialize it even.
- Check new wm_jobs.c for more explanation. Jobs API is still
under construction.
Fun: BLI_addtail(&wm->jobs, steve); :)
Put Node shader previews back using wmJobs
- Preview calculating is now fully threaded (1 thread still)
- Thanks to new event system + notifiers, you can see
previews update even while dragging sliders!
- Currently it only starts when you change a node setting.
Warning: the thread render shares Node data, so don't delete
nodes while it renders! This topic is on the todo to make safe.
Also:
- bug in region initialize (do_versions) showed channel list in
node editor wrong.
- flagged the channel list 'hidden' now, it was really in the
way! This is for later to work on anyway.
- recoded Render API callbacks so it gets handlers passed on,
no globals to use anymore, remember?
- previewrender code gets now so much nicer! Will remove a lot
of stuff from code soon.

Sorry, three commits in one, became difficult to untangle..
Editors Modules
* render/ module added in editors, moved the preview render code there and
also shading related operators.
* physics/ module made more consistent with other modules. renaming files,
making a single physics_ops.c for operators and keymaps. Also move all
particle related operators here now.
* space_buttons/ now should have only operators relevant to the buttons
specificially.
Updates & Notifiers
* Material/Texture/World/Lamp can now be passed to DAG_id_flush_update,
which will go back to a callback in editors. Eventually these should
be in the depsgraph itself, but for now this gives a unified call for
doing updates.
* GLSL materials are now refreshed on changes. There's still various
cases missing,
* Preview icons now hook into this system, solving various update cases
that were missed before.
* Also fixes issue in my last commit, where some preview would not render,
problem is avoided in the new system.
Icon Rendering
* On systems with support for non-power of two textures, an OpenGL texture
is now used instead of glDrawPixels. This avoids problems with icons get
clipped on region borders. On my Linux desktop, this gives an 1.1x speedup,
and on my Mac laptop a 2.3x speedup overall in redrawing the full window,
with the default setup. The glDrawPixels implementation on Mac seems to
have a lot of overhread.
* Preview icons are now drawn using proper premul alpha, and never faded so
you can see them clearly.
* Also tried to fix issue with texture node preview rendering, globals can't
be used with threads reliably.

Blender Internal Render in viewport
Because of our release soon, feature has been added behind the Debug Menu.
CTRL+ALT+D and set it to -1. Or commandline --debug-value -1.
When debug set to -1, you can put the viewport to 'render' mode, just like
for Cycles. Notes for testers: (and please no bugs in tracker for this :)
- It renders without AA, MBlur, Panorama, Sequence, Composite
- Only active render layer gets rendered. Select another layer will re-render.
- But yes: it works for FreeStyle renders!
- Also does great for local view.
- BI is not well suited for incremental renders on view changes. This only
works for non-raytrace scenes, or zoom in ortho or camera mode, or for
Material changes. In most cases a full re-render is being done.
- ESC works to stop the preview render.
- Borders render as well. (CTRL+B)
- Force a refresh with arrow key left/right. A lot of settings don't trigger
re-render yet.
Tech notes:
- FreeStyle is adding a lot of temp objects/meshes in the Main database. This
caused DepsGraph to trigger changes (and redraws). I've prepended the names
for these temp objects with char number 27 (ESC), and made these names be
ignored for tag update checking.
- Fixed some bugs that were noticable with such excessive re-renders, like
for opening file window, quit during renders.
