Cleanup: Move eraser brush draw to function and avoid duplicated code

Fix problem with Eraser cursor size

The problem was the internal red area was not using the same size of the external lines.

Change Eraser brush to use brush radius not global value

The old configuration uses a global user prefs value, but now must be the brush size.

Still need to fix the problem when resize size of the brush.

Enable right cursor for Erase brush

The cursor must show that you are using the eraser

Fix Cycle standalone build.

WIP: New Eraser brush

This new brush is equal to the old eraser, but it makes the interface more consistent.

Still need more work to adapt all eraser features, limit other actions not related to eraser and brush switching.

Clay: Perf: Early out of SSAO if there is no need for it.

DRW: Refactor simple instancing.

Instead of creating a new instancing shading group without attrib, we now have instancing calls. The benefits is that they can be culled.
They can be used in conjuction with the standard and generate calls but shader must support it (which is generally not the case).
We store a pointer to the actual count so that the number can be tweaked between redraw.

This will makes multi layer rendering more efficient.

Object Mode: Make use of optimized DRW_shgroup_call_object_add

DRW: Add DRWMatrixState to manage all matrices together.

Eevee: Cleanup & fix Warnings.

Eevee: Make use of culling when rendering the shadowmaps.

Fix build errors in Linux

Cleanup previous commit

Make more compact the code

Hide Draw cursor when Eraser is enabled

If the eraser is enabled, the little color dot used as cursor for drawing must be hidden and replaced by dash line circle cursor only.

Merge branch 'master' into blender2.8

Remove duplicate line

This line had to be removed in a previous commit.

Depsgraph: Fix dependency cycle when ID prop drives ID property

Introduced explicit ID property node for driers in depsgraph,
so it is clear what is the input for driver, and what is the
output.

This also solved relations builder throwing lots of errors
due to ID property not being found.

Merge branch 'blender2.8' into greasepencil-object

Fix again grease pencil modes after merge
