GPencil: Custom drawing/status for curve pen

This commits adds custom drawing for the curve pen.
Initially this will draw the handle while draging.
This commits also adds a modal keymap to the operator making the
status text possible. Now the user can see what key does what in
each of the states.

Merge branch 'temp-compositor-scheduling' into temp-compositor-single-threaded-operation

Merge branch 'master' into temp-compositor-single-threaded-operation

Fix crash when using TBB.

Fix: Loosing Workerthreads During Execution.

GPencil: Fading control for opacity/thickness modifier updated.

fix gcc build errors

Merge branch 'master' into cycles_texture_cache

Granularize attribute updates.

When any attribute is removed from its AttributeSet, the device data for
every attribute type has to be updated. This makes it so we only update
the appropriate device data array.

Fix last commit to handle symmetrical brushing properly

* Dyntopo now has its own brush spacing. This is a huge performance
boost for brushes with fine spacing, e.g. the clay brush.

Default cache size to 4096 Mb.

EEVEE: Film: Filtered accumulation with panoramic projection support

This commit adds the Film class that handles accumulation of color and
non-color data using arbitrary projection and filter size.

A weighted accumulation (sum) is done into a data buffer with an
additional weight buffer. The sum being per pixel, it allows the input
textures that are not aligned with the output pixel grid.

Panoramic projection works by rendering a cubemap (6 views) of the scene
at the camera position. The Film filter pass then gather the pixels
using the correct Panoramic projection ensuring correct Anti-Aliasing.

For Non-color data (depth, normals) we only keep the closest value to
the target pixel center (simulating a filter size of 0).

Color data is accumulated in a log space to improve AntiAliasing output.
This is hardcoded for now.

Larger filters have poor performance but are very fast to converge.

Code Wise: This commit rename some modules to avoid possible confusion
and have better meaning. Use namespace instead of prefixes.

Added a new eevee_shared.hh file to share structure and enum definitions
between GLSL and C++.

Finished curvature rake.

DNA: Camera: Add panoramic types and parameters

These are direct copy of Cycles parameters. Cycles parameters
unification will be done separately.
