Cleanup: Reduce indentation

Having up to nine levels of indentation make this function hard to
follow. Instead of indenting the rest of the loop for a simple special
case, just continue.

Merge branch 'master' into xr-actions-D9124

XR: Add raycast option to ignore non-selectables

Useful when user does not want non-selectable objects to block
selectable objects in raycast result.

Fix unclear tooltip for the Affect Transform option of constraints.

Keymap I/O: Add "exec" versions of import/export

The new "exec" functions are added for the sake of the VR Scene
Inspection add-on and do not affect the behavior of the existing
keymap I/O functions.

keyconfig_export_as_data_exec() enables exporting a specified keymap
instead of all user-modified keymaps. The VR add-on uses this to
selectively export the "XR Session" add-on keymap.

keyconfig_import_as_data_exec() enables adding keymap data to an
existing keyconfig instead of creating a new keyconfig. The VR add-on
uses this to add the "XR Session" keymap to the add-on keyconfig.

XR: Improve error logs when creating actions

Include action set name in case multiple action sets have an action
with the same name.

Previous commit forgot to guard some things with #ifdef WITH_GMP.

Removed debug output.

UsdPreviewSurface shader network import.

Added experimental code to import UsdPreviewSurface shaders
as Blender Principled BSDF node networks.

Improve speed of Constrained Delaunay Triangulation with exact arith.

By using floating point filters, the speed improves by a factor of 2 to 10.
This will help speed up some cases of the Exact Boolean modifier.
Changed the interface of mpq2::isect_seg_seg to not return mu, as it was
not needed and not calculating it saved 15% time.

GPencil: Replace NULL with C++ nullptr

Merge branch 'greasepencil-object' into greasepencil-io

GPencil: Remove SVG storyboard support

We can include it again in the future, but now it's better to remove it.

Merge branch 'master' into greasepencil-object

Merge branch 'blender-v2.91-release'

GPencil: Fix unreported assert when use select Box in single point strokes

The assert was when use segment selection mode.

Cleanup: Declare variables where initialized

Reduce variable scope, and in a few cases, use bool instead of int.

Add refresh button for external repositories

External repositories (ie all repositories but the "Current File" one) need
manual refreshing to reflect changes. So show a button for that in the Asset
Browser header, attached to the repository selector.

Cleanup: Make header layout definition a bit cleaner

Fix crash when showing search menu outside of File/Asset Browser
