Fix T49181: Movie clip animation lost when invoking action which reloads the clip

Was a bug since the very beginning of movie clip animation support
which was done on Feb 2012.

Movie clip: Add missing animation data RNA declaration

Was missing since the beginning of the days.

Fix T49172: mixdown sound op not exporting full length

Thanks Flavio Perez for the fix.

Fix compilation error caused by wrong array initialization

We usually don't silence migh-be-uninitialized warning (which is the only
thing which could explain setting matrix to all zeroes) so we can catch
such errors when using tools like Valgrind.

I don't get warning here and the initializer was wrong, so removing it.

If it-s _REALLY_ needed please do a proper initialization.

GPencil UI: Move the "quick toggles" for colors into their own row below the list

Previously, they were in a column alongside the list, but because the lists were
rarely that long, there would always be a large gap left below the list.

Fix: Some settings (e.g. "volumetric strokes") from old files were not getting correctly ported to GPv2

Code Cleanup: Fixes for some issues noticed during previous fix

Fix: GPencil Paste couldn't be used to paste strokes from one datablock to another

This was because the poll callback was checking for the presence of an active layer.
If you just create an empty datablock and try to paste, nothing would happen.

However, this check was kindof redundant anyway, as the operator would add a layer for
you if it didn't find one.

Small optimisation: Only calculate the inverse_diff_mat once per stroke instead of for every point

(Later this calculation should be moved into the iteration macro instead, since
it only needs to be applied once per layer along with the diff_mat calculation)

GPencil: "Reproject Strokes" operator

A common problem encountered by artists was that they would accidentally move
the 3D cursor while drawing, causing their strokes to end up in weird places in
3D space when viewing the drawing again from other perspectives.

This operator helps fix up this mess by taking the selected strokes, projecting them
to screenspace, and then back to 3D space again. As a result, it should be as if
you had directly drawn the whole thing again, but from the current viewpoint instead.
Unfortunately, if there was originally some depth information present (i.e. you already
started reshaping the sketch in 3D), then that will get lost during this process.
But so far, my tests indicate that this seems to work well enough.

GPencil: Include basic brush settings in "Grease Pencil Settings" panel for 2D Editors

After the GP v2 changes, it wasn't possible to easily set the thickness of strokes
if you didn't know about the pie menus already. This just exposes the same set of
settings.

Code Cleanup: Just some fixes for whitespace/typos that I noticed while working on other stuff

GPencil UI: Make "Tint" settings take full width of panel in 2D editors

Parenting options are not visible there (i.e. they're only for the 3D view),
so reserving space that isn't going to be used in those editors doesn't really
make much sense. Furthermore, those property regions are often quite narrow
too, so it doesn't help too much to keep these settings so narrow there.

Fix T49163: let Cycles only hide particles with missing motion data, not regular objects.

Fix T47639: OpenGL render with smoke and fire incorrect when using
transparency.

The issue is that we are rendering to a 0..1 clamped sRGB buffer with
unpremultiplied alpha, where the correct thing to do would be to render
to an unclamped linear premultiplied alpha buffer. Then we would just
make fire purely emissive without affecting the alpha channel at all,
but that doesn't work here.

So for now, draw fire and smoke separately using different shaders and
blend modes, like it used to before the smoke programs were rewritten
(see rB0372b642).

Fix T49167: Normals in wrong coordinate space when adaptive subdivision is used

Meshes with Cycles subdivision were being transformed to world space leading to
normals to sometimes be calculated in that space, while they should be in
object space. Also caused dicing to happen at the wrong rate for scaled meshes.

Fix missing viewport update changing BI lamp shadow method

OpenGL: use new uniform color functions

Color picker code motivated these convenience functions. looks much better now.

Gawain: convenience functions for uniform color

Application code can pass ubytes, Gawain converts to float vec4 expected by shader.

For now the conversion is simple linear. We can add sRGB support later if needed.

GPencil: Added entry for the "Select Strokes Using Active COlor" operator to the Colors panel dropdown

It was already present in a few of the Pie Menus, but it was hard to find it,
so I've included it here too for good measure.
