New Window Operator (to replace Duplicate Window)

A user doesn't want to necessarily create a new Screen only because she
wants a new window.

This patch allows the user to pick the screen to use for the new Window.
If the screen picked is the active one, it duplicates it (as the old
behaviour in Blender).

Cycles: Make MESA compiler more happy

While this compiler is not officially supported yet, getting it to work is
a nice thing because more and more AMD cards will fall under MESA driver.

It's also nice to use explicit comparison with NULL, which makes it more
clear whether variable is a boolean or pointer. Even Rust enforces this!

Patch by Ian Bruce with own modifications.

UI: expose mesh conversion in apply menu

The mesh convert operator can 'freeze' a mesh
(WYSIWYG, modifiers, shape keys etc).
However its not very obvious that the way to perform this
operation is to convert a mesh to a mesh.

Expose this as 'Visual Geometry to Mesh' in the 'Apply' menu,
since this is where users might expect to see it.

Comments: minor clarification

Clay Engine: Fix missing grid

Clay Engine: Mode engine templates.

Standard Engine layout easy to extend.

Note that most of the work will also happen in mesh_render.c to create geometry batches.

fix T50923: Inconsistent default values and wrong order of parameters in api call

Fix T50930 Typo in 'jpeg2k_codec' description

BMesh: rename cryptic functions

Use expanded names for bmesh primitive operations
(urmv jvke semv jfke).

Use 'bmesh_kernel_' prefix,
these functions aren't intended for wide use so favor readability.

Remove BM_face_vert_separate,
it wasn't used and only skipped step of finding correct loop of face.

Cleanup: style

UI: Always open enum-search popups with empty search string

It might be useful to keep the search string stored in some cases, but
in most it's not useful but confusing. Especially if the string is taken
from a menu showing a different enum.

Fix T50788: blender startup crash on macOS with some types of volumes available.

Fix T50628: gray out cycles device menu when no device configured only for GPU Compute.

OpenGL: Convert drawobject.c (cont)

All remaining 28 deprecated calls are derivedMesh related.
