GPUShader: Add name for debugging & identifying shaders.

Eevee: Fix missing UBO binds.

Some of them are unecessary and should be removed from the shader instead.

But for now we need a quick fix for the crashes happening on some platforms.

See T55475.

Fix missing type for material arry

This function was called by RNA Api and had grease pencil object type missing.

Fix wrong RNA Api parameter definition

Depsgraph: fix some DEG queries crashing with new, empty graph.

Calling code is responsible to check on NULL pointers here, or ensure
is does have a fully built and evaluated depsgraph, but this should
never crash in DEG queries themselves.

Fix assert in UI string trimming code when we have 'protected' right part.

UI: Move thickness before frame lock in Annotation Panel

The thickness is more important and must be below list of annotation layers.

Cleanup: use dictionary for icon lookup

UI: show all particle brush settings in topbar

Also show particle brush in tool-properties panel.

UI: show particle radius & strength in topbar

Subsurf: Better crease which represents sharp edges

Enabled infinite sharp patches for topology refiner and evaluator,
which allows to have sharp edge at first subdivision level.

Also tweaked crease export from Blender to OpenSubdiv to have more
artistic control over the whole 0..1 range.

Tool System: initial particle system support

Tool System: sync changes from changes to brushes

Changing a brush now updates the tool.

Merge branch 'master' into blender2.8

RNA: make particle enum public

Fix T56199: Crash on Annotation in (VSE) Image Preview

In some cases (e.g. using old userpref settings/keymaps)
it was possible to trigger a crash when the wrong GP/Annotation
operators were triggered in the wrong contexts (e.g. using
the old GPENCIL_OT_paint in annotation-only contexts like
all the 2D editors).

This commit resolves several issues that were caused by sloppy
code-churn + features that had been hacked on.

Dev Tooling: Instrument motion path calculation operator (for bones) to collect timing data

This will be useful for checking on the progress of our optimisation
efforts, and to generate some nice stats for later.

Armature Panel Tweaks - Motion Paths/Ghosting

Since most animators find Motion Paths more useful than Armature Ghosting:
* Move Motion Paths before Ghosting settings (less scrolling)
* Collapse Ghosting panel by default
* Open Motion Paths panel by default instead

UI: Slightly larger action zone for corner resizing

Pretty minor, from 0.6 to 0.8, but the improvement is noticeable
especially when using a stylus, without overlapping too much with
the buttons and dropdowns in headers.

UI: Group similar Grease Pencil brush settings
