Fix slicing with negative indices

Negative indices that remained negative after adding the sequence length
caused incorrect slicing.

With the default scene for example:

bpy.context.scene.objects[-4:2]

Gave a different result to:

tuple(bpy.context.scene.objects)[-4:2]

Clamp indices above zero so loops that step forward works as intended.

Fix fix invalid index use for edit-mesh laplacian smooth

Only vertex indices were ensured to be correct.

Fix T90477: Cursor vertex snapping not working in UV editor

`t->obedit_type` is read to indicate if we are in uv edit mode.

Also fixes a crash introduced in {rBdd14ea18190ff27082009f73a556569a43377a71}.

Cleanup: return True/False from gpencil toolbar function

This was returning None/False which could cause problems in the future.

Cleanup: indentation

Cleanup: use 'cls' for class methods first argument

Cleanup: remove redundant imports

The module was importing it's own functions.

Fix text object inserting multiple characters with a selection

`bpy.ops.font.text_insert(text="multiple characters")` wasn't working.

When the text is selected does not correctly insert multiple characters.

- When the text was selected from left to right,
the cursor only move one position next to the selected text.
- When the text is selected from right to left,
a part of the selected text remain.

Fix incorrect position of disks in hinge constraint

Cleanup: Panels for drawing constraints

USD IO: fix compiler warnings and errors

Fixed warnings and errors for linux and darwin
builds. Also fixed copyright date in
usd_light_convert.cc.

Cleanup: grease pencil app-template versioning

- Remove check for screens being None as this would raise an error.
- Replace loop over `area.spaces` with `area.spaces.active`.
- Loop over grease pencil data directly instead of accessing
through the scenes objects.
- Split versioning into functions.
- Use `update_factory_startup_*` prefix for function names
as this isn't versioning existing files.

Cleanup: avoid using context in versioning code

Also extract versioning into a function that makes it's purpose clear.

UI: Show Mask Display Options Conistently

This commit makes the display options for mask only show in the header for the clip and image editors.
Prior to this change they would display in the header for the clip editor and in the sidebar for the image editors.

UI: Sequencer: Fix placement of display options in sequencer & preview mode

This commit does two things, first it removes the proportional editing tool settings.
This is not accessible code and is has not been used since the grease pencil/annotations changes in 2.8.

Second, this patch reorders the if statements so that the display options are always shown on the rightside.

Cleanup: Remove stale/dead code

This seems to be really old code from 2.4 or earlier.
I was unable to find when it was removed gitk and git blame both couldnt find anything.
However, it is safe to say that this code is long gone.
