Cleanup: Armature

Armature: Speedup by removing unecessary check

drw_batch_cache_generate_requested() is only needed when the geom needs to be
created.

Went from 37fps to 47fps with artificial testcase (lots of bones with one custom shape). Baseline 2.79 is 24fps.

Also fix the drw_shgroup_bone_custom_wire.

Fix T58966 Sculpted changes dissapear visually when selecting a second object

Display sculpt mesh if there is a sculpt session.

GPUSelect: Don't read depth on every draw

If the draw uses the same id as the previous draw, there is no need to read the depth
buffer at this point, avoiding a CPU-GPU sync bubble.

Fixes T62511 Selection is significantly slower in production scenes.
With this patch glReadPixels is not the bottleneck. Regular drawing Is still very
slow so I would suggest fixing the regular drawing first before trying to
improve the selection algorithm.

Fix T62880 Severe FPS drop with multiple bone shapes

Fix instancing batches not being reused by custom bone shapes.

Drawing thoses is now faster than 2.79 (40fps instead of 30fps)

Fix T63896: Removing Drivers in Python Leads to Crash

Adding and removing drivers must always tag relations for update.

Merge branch 'master' into temp-topbar-ui

Fix T63897: GPencil Material Presets showing error

This error was introduced in a previous commit with the rename of the parameter.

Also added some missing values.

Keymap: Support shift-click to select multiple reports

Also support drag for box-select, matching the outliner.

Cleanup: unused variable warning

Fix T63784 Eevee : Black Diffuse with Principled BSDF and Mix Shader

This was cause by the SSS energy being lost when using SSRefraction. Also the mix
shader did not merge the discarded SSS light into the radiance.

Cleanup: Node shader texture image

AVI: Fix buffer overflow

That was causing crashes when loading uncompressed avi files created with blender 2.79.

Fix T63605: Assert squeezing a template_curve_mapping in a panel to
almost zero horizontally

Reviewers: brecht

Maniphest Tasks: T63605

Differential Revision: https://developer.blender.org/D4690

Changed the layout of the directory buttons, display mode panel and the "Create new directory" button

Text editor: convert tabs to spaces on paste

If the Tabs as Spaces settings is enabled for the text block. This avoids
issues with inconsistent indentation when pasting Python code from another
source.
