Cycles: Resize light_data after possible light removal.

Cycles: Remove Emission shaders from the graph if color or strength is 0.

UI: Copy to selected nodes now filtered by type

Was needed because sockets are very generic type which would match on unrelated values.

Cleanup: Avoid temp variable in portal sampling code.

Cycles: Cleanup: use generic utility function to set kernel arguments

Cycles: Inline sizeof of elements needed for the split kernel

No need to store them in the class, they're unlikely to be changed
and if they do change we're in big trouble anyway.

More appropriate approach would be then to typedef this things in
kernel_types.h, but still use inlined sizeof(),

Cleanup / Cycles: De-Duplicate Portal data fetch and side check.

Clip editor: Selecting curves in graph view always extends tracks selection

Was actually an old TODO, hopefully solved now in a way so everyone is happy.

Clip editor: Deselecting with shift-LMB does not work in graph view

Fix T44683: Unable to mute movie clip when using stabilized display

Fix T44689: New Depsgraph crash

Simple highschool rated issue -- uninitialized variable :)

Project Paint: enable old bleed UV calculation

Was disabled because other values weren't quite right.

Project Paint: resolve ugly bleed artifacts

Use the bilinear reverse to find the pixel to bleed from.
Was using pixel space which didn't work well.

Project Paint: simplify uv bleed factor calc

Fix T39775: Skin modifier crash

Cleanup: reduce scope for win32, Linux vars

Duplicate Render->RenderData.views for thread safety (as we do for layers)

This fixes nothing at the moment, but better safe than sorry since there
are still a few strange multiview issues around.

UI: check visible layers when reading context

This resolves a problem where selected items edited for multi-value-editig
could include objects not in any visible views (unlocked layers, local view... etc).

UI: multi-value-edit, distable alt+lmb on sliders

UI: multi-value-edit, tint button while editing

Currently re-uses node-flag (which is only used to tint color too)
