Fix T65837: Zoom Axis is not working in the Node Editor

It was already fixed for the mouse in
bcda8cc89b88c999ff64edcc19973d6289bcbf2a, T65837
now the same logic is applied for the track-pad.

Ref D8685

Fix T73575: Zooming out a lot faster than zooming in

- Zooming out a lot faster than zooming in,
it had the wrong aspect ratio, make all the preparations
with the factors instead of deltas.
- Improved following the `zoom_invert`
(should not apply to `MOUSEZOOM`) and "trackpad natural scroll"
preferences.
- `zoomfac` adjustment, same as in `view_zoomdrag_modal`.

Ref D8686

UI: Fix various issues with UI text

- Use the name "Point Cloud" instead of "Pointcloud"
- Fix a typo in UV_OT_smart_project.
- Use the name "Install Light" to for the installation
operator for MatCaps, HDRIs, and Studio Lights.

Fix T83094: Alternate rows in the Sequencer are green (macOS)

The issue is that `UI_GetThemeColorBlendShade4fv()` creates a color
with alpha, but there is not any background underneath to blend in with.

The solution is just to draw an opaque background first, which also
halves the number of rects to draw. Note that the brighter rows get
very slightly darker after this change.

Fix unreported: Sequencer grid lines are not drawn

By design, there should be lines between the alternating horizontal
stripes in the Sequencer. But currently they are all drawn in one place,
on top of each other. Mistake in rBfae895125efe.

UI: Cleanup spelling of compound words

Approximately 138 changes in the spelling of compound words
and proper names like "Light Probe", "Shrink/Fatten", "Face Map".
In many cases, hyphens were used where they aren't correct, like
"re-fit". Other common changes include:
- "Datablock" -> "data-block"
- "Floating point" -> "floating-point"
- "Ngons" -> "n-gons"

These changes help give the language used in the interface
a consistent, more professional feel.

Cleanup: Fix capitalization in various UI strings

Approximately 195 changes of capitalization to conform to MLA title style.
UI labels and property names should use MLA title case, while descriptions
should be capitalized like regular prose, generally with only the start of
a sentence capitalized.

UI: Fix text padding in some list widgets

Normally, pure text buttons have no padding at their edges so they
align with edges of buttons, see D9058. However, in several cases
there are labels aligned to the right side of a list widget row,
so they're missing padding against the right edge.

The fix is to use emboss = 'NONE' for such labels, which changes
the drawing style, adding padding on the right edge. (Normally so
labels aligned with the text from non-embossed buttons). This is
not necessarily intended, but it works properly.

For more information, see the revision.

UI: Reorder enums in render results image editor header

The convention is to put the label at the bottom of the enum, or in the
spot furthest away from the button. This commit reorders the items in
the "Slot", "Layer", and "Pass" menus to be consistent with this
convention. It also reorders the numbering so that higher numbers are
lower.

The original patch was by Adrian Newton (@TFS), with slight changes
and additions.

UI: Don't use abbreviations in label text

Expand abbreviations for words like "Bright" (instead of "Brightness"),
"Premul", "Lib", "Dir", etc.
