Legacy OpenGL has a matching Vertex3fv for every Vertex3f, and so on. Add something similar to Gawain, just for a few common functions. Might add more as the need arises.
If the ruler is saved, a new color was created for each ruler. With the
change, a color is created for the first instance, and it reused in the
following instances. The default color is the current default color for
GP.
These are intended for very simple drawing. No lighting etc.
Shares some fragment code with the 2D shaders.
Similar to their 2D counterparts, but are not combined because of
future plans for separate 2D & 3D matrix stacks.
It's becoming annoying to have public API dependent on build type
and everything. Let's just always have API defined and do stubs
in the function implementation instead.
Current implementation more or less indiscriminately links physics
objects to colliders and forces, ignoring precise details of layer
checks and collider groups. The new depsgraph seemed to lack some
such links at all. The relevant code in modifiers suffers from a
lot of duplication.
Different physics simulations use independent implementations of
collision and similar things, which results in a lot of variance:
* Cloth collides with objects on same or visible layer with dupli.
* Softbody collides with objects on same layer without dupli.
* Non-hair particles collide on same layer with dupli.
* Smoke uses same code as cloth, but needs different modifier.
* Dynamic paint "collides" with brushes on any layer without dupli.
Force fields with absorption also imply dependency on colliders:
* For most systems, colliders are selected from same layer as field.
* For non-hair particles, it uses the same exact set as the particles.
As a special quirk, smoke ignores smoke flow force fields; on the other
hand dependency on such field implies dependency on the smoke domain.
This introduces two utility functions each for old and new depsgraph
that are flexible enough to handle all these variations, and uses them
to handle particles, cloth, smoke, softbody and dynpaint.
One thing to watch out for is that depsgraph code shouldn't rely on
any properties that don't cause a graph rebuild when changed. This
was violated in the original code that was building force field links,
while taking zero field weights into account.
This change may cause new dependency cycles in cases where necessary
dependencies were missing, but may also remove cycles in situations
where unnecessary links were previously created. It's also now possible
to solve some cycles by switching to explicit groups, since they are
now properly taken into account for dependencies.

For now simply reshuffle option so they keep proper dependency flow.
Benefits:
- Has an ability to hide tracks lists to work with other sliders around.
Could be really handy to quickly get rid of lenghty lists.
- From a feedback seems to be fitting workflow better.
Things to doublecheck on:
- Feels a bit misordered: first you define whether one want to have
rotation stabilized, then have tracks, then scale options.
While this follows dependency flow (which is really good and which
we should not violate) it has weird feeling on whether things are
really where they have to be.
- Autoscale controls visibility of max-scale, can we just make it
active/inactive instead?
- Autoscale replaces slider with label. Can it be disabled slider
instead to reduce visual jumping (disabled slider prevents user
input)
Hopefully we'll still want to have collapsable box after re-iterating
over this points, so we don't waste bits in DNA.

See this video for UI explanation and demonstration of usage
http://vimeo.com/blenderHack/stabilizerdemo
This proposal attempts to improve usability of Blender's image stabilization
feature for real-world footage esp. with moving and panning camera. It builds
upon the feature tracking to get a measurement of 2D image movement.
- Use a weighted average of movement contributions (instead of a median).
- Allow for rotation compensation and zoom (image scale) compensation.
- Allow to pick a different set of tracks for translation and for
rotation/zoom.
- Treat translation / rotation / zoom contributions systematically in a
similar way.
- Improve handling of partial tracking data with gaps and varying
start / end points.
- Have a user definable anchor frame and interpolate / extrapolate data to
avoid jumping back to "neutral" position when no tracking data is available.
- Support for travelling and panning shots by including an //intended//
position/rotation/zoom ("target position"). The idea is for these parameters
to be //animated// by the user, in order to supply an smooth, intended
camera movement. This way, we can keep the image content roughly in frame
even when moving completely away from the initial view.
A known shortcoming is that the pivot point for rotation compensation is set to
the translation compensated image center. This can produce spurious rotation on
travelling shots, which needs to be compensated manually (by animating the
target rotation parameter). There are several possible ways to address that
problem, yet all of them are considered beyond the scope of this improvement
proposal for now.
Own modifications:
- Restrict line length, it's really handy for split-view editing
- In motion tracking we prefer fully human-readable comments, meaning we
don't use doxygen with it's weird markup and comments are supposed to
start with capital and end with a full stop,
- Add explicit comparison of pointer to NULL.

EXT_gpu_shader4 lets us say “noperspective” in GLSL #version 120 just
like in later GLSL.
Mac shader now matches modern GLSL available on other platforms.
Reduces noise from --debug-gpu so we can spot serious errors.
Blender 2.7x uses OpenGL 2.1, we don't care if features are deprecated.
I'll re-enable these warnings for blender2.8 after next merge.
When running blender --debug-gpu
Display which debug facilities are available. One of these, in order of preference:
- OpenGL 4.3
- KHR_debug
- ARB_debug_output
- AMD_debug_output
All messages are logged now, not just errors. Will probably turn some of these off later.
GL_DEBUG_OUTPUT_SYNCHRONOUS lets us break on errors and backtrace to the exact trouble spot.
Callers of GPU_string_marker no longer pass in a message length, just the message itself (null terminated).
Apple provides no GL debug logging features.
Helps most when real-world units are used.
Previous code started at the smallest visible unit (e.g. Inches) then
followed to Feet, Yards, Chains, Furlongs, Miles. Always to the largest
unit of the set, even though most would be way off screen.
New code knows whether it skipped any grid lines for the next unit to
fill in, can stop once all lines are on screen.
Previous commit works on Windows, found some issues after trying on Mac.
- benign warnings about && within ||
- replaced nearbyint() with round() to avoid floating point environment
surprises
- remquo function appears to be broken on Mac (!) results were way way
off. Replaced with simple division.
- minor tweaks to debug output
Work toward T49043, with a side of client vertex arrays.
Not a straightforward port from glVertex to immVertex since Gawain needs
to know how many vertices we'll be drawing *before* we start drawing.
Fixed these not-so-great aspects of grid drawing:
- coarse grids would draw atop some lines from the finer grids
- visible axes would draw atop lines from coarse grid
- axes were drawn even if they weren't in view
- terrible misuse of vertex arrays
- each line issued its own draw call
New code draws each line exactly once. The entire grid is one draw call.
Bonus: I had to / got to learn how the units system works!
New value of 4MB should handle our needs without taking up too many GPU
resources.
Old value of 1KB was for observing what happens when the buffer fills up
and we need to flush and start a new one.
When updating the max values under stiffness scaling, they clip at the normal stiffness values
as expected, however when updating stiffness values, you could set them higher than the max
values, and the max values weren't updated accordingly. As the stiffness scaling computes using
the absolute difference between the max values and the stiffness values, you got higher
stiffnesses in scaled areas even though your max is actually lower than the normal stiffness.
This diff fixes that behaviour, by updating the max values to be equal to the stiffness whenever
you set a higher stiffness than the max value.
Also, I have initialized the max values to the same as the stiffnesses, as they were previously
just set to zero, and caused the same problem described above.

Node tree update calls in the middle of a socket loop are dangerous, they can change sockets
on group nodes and link instances in particular. Updates should only happen after the operator
has finished.
Simply removed the extra convenience check for validity now. Worst case an invalid (red) link
is created which can be removed by the user as well and should simply be ignored by node systems.
The update system in nodes needs a complete rewrite to handle complex cases like this, where an
operator may need to react to changes during its execution.
GPencil conversion would just always run for file version 2.77.3. This wasn't an issue in master, but possibly for other branches that used the 2.77.3 block.
Wasn't aware that you have to add the asterisk for pointers either, this is kinda weird. Anyway, it's running correctly now.
Getting this ready for Gawain treatment.
Removed setlinestyle(0) -- solid lines are the default, hope this isn't
really needed.
Eliminated redundant math.
Arithmetic is still double precision, passed to OpenGL as single
precision. Even though it said GL_DOUBLE before, values were converted
to GL_FLOAT internally.
Use C99-isms for declaring variables close to where they're used.
Minor whitespace tweaks.
New dependency graph puts materials to the graph in order to deal with animation
assigned to them and things like that. This leads us to a requirement to update
relations when slots changes.
This fixes: T49075 Assignment of a keyframed material using the frame_change_pre handler
doesn't update the keyframe using the new dependency graph
This is mainly required for the new dependency graph where non-object
datablocks are a part of dependency graph.
This solves issue when making mesh shared by multiple objects a single
user one.
Point cache read code contains checks designed to prevent it reading
stale data when the relevant simulation code should instead compute
the next frame from the previous one. However in some situations like
motion blur subframes the simulation can't possibly do it and just
exits. This causes completely incorrect motion blur at or after the
last cached frame.
To fix, add a parameter that tells the cache code whether it should
apply the checks and exit, or read what it can even if stale (true
means exactly same as old behavior).
Doing this in cache rather than clamping the frame number better in
the caller lets it handle the case of incomplete cache that stops
before the official last frame.
