The underlying functions used to calculate the shrink are the same used in meshes.

Use arrays for wmEvent coordinates, this quiets warnings with GCC11.
- `x, y` -> `xy`.
- `prevx, prevy` -> `prev_xy`.
- `prevclickx, prevclicky` -> `prev_click_xy`.
There is still some cleanup such as using `copy_v2_v2_int()`,
this can be done separately.

Ref D12901
When joining two strokes in paint mode using the auto merge option, the join was very hard if the thickness was too different.
This patch adds a smooth to the join in order to get better transition.
Also fixed the problem to join existing strokes very far from actual stroke.
Some cleanup and rename of old code is included in order to make code more readable.

When interpolate, the stroke order was not correct because it was assumed the GHash iter would return the items in the same order of insertion, but this is false.
Now, a list is used to keep the order of the strokes and the Hash is used to get the relationship between strokes as before.
Before only it was only possible interpolate frames of `Keyframe` type. Now all types except `Breakdown` can be used.
`Breakdown` cannot be used because it would be impossible interpolate two times because the extremes of the interpolation would change and the clean operator would not work.
Multiply the two number together. If the sign of the result is positive, then the sign was the same. If the sign of the result is negative, then the signs were different.
Improved the calculation of the distances and changed the variable names to make it more readable.
Still, there are some corner cases that could be not handled properly, but we keep as is to test more real drawings to analyze if the small number of corner cases needs to be fixed or not.
Following with the changes included to interpolate strokes of different number of points, a full review has been done in the interpolation tools.
* Interpolate now is a tool and not an operator. It was not logic to have this tool as a button.
* Interpolate tool parameters have been moved to topbar.
* Interpolate popover has been removed from topbar and interpolate `Sequence` operator has been moved to grease pencil menu.
* Interpolate Sequence now include a Redo panel.
* Interpolate tool now allows to select the strokes by pairs. This allows to interpolate any stroke with any stroke and not as before that it was only possible by drawing order. If no stroke is selected, the interpolation is done as before.
* Now is possible interpolate again if a previous keyframe exist. Before, it was impossible to interpolate two times in same frame and this made impossible to do the interpolation by groups of frames.
* New automatic option to `Flip strokes` if the stroke and end are not in the right position. Also the flip can be set manually for corner cases.
* Cleanup of menus related to interpolate.
* Fixed some bugs and removed parameters from scene because now all are tool or operator contained.
* Some code cleanup and function renames.
This commit also includes the some codebase to future implementation of the concept `Vertex Active` that now does not exist in grease pencil.
In two cases the percentage property was actually used incorrectly, as
pointed out in T82070. The range was [0, 1], but the properties were still
displayed as percentages.
There is a preference to control whether to display factors or
percentages, so it usually doesn't make sense to manually define
properties as percentages.

Use the BKE_gpencil_stroke_uniform_subdivide function to subdivide strokes
before interpolation. When the target/source stroke is smaller than the other
stroke, it is subdivided until the lengths match. This improves the overall quality
of the interpolation of different sized strokes.

This patch is the result of the GSoC 2020 "Editing Grease Pencil Strokes
Using Curves" project. It adds a submode to greasepencil edit mode that
allows for the transformation of greasepencil strokes using bezier
curves. More information about the project can be found
here: https://wiki.blender.org/wiki/User:Filedescriptor/GSoC_2020.
Sometimes interpolate all frames is not convenient and it's better, for example, interpolate in twos.
The new parameter allows to define the number of frame for each step, by default is set to 1 as before.

This was due some strokes could be tagged and as the layer was locked, the strokes were not untagged and removed when all tagged strokes are removed.
The tagged strokes are used as temp ghost of the interpolation and removed at the end of the interpolation.
In some situations the stroke could be tagged and this tag was used to delete the interpolated strokes.
Now, the frames used as interpolated range are untagged before creating the interpolated strokes.
Follow up of b2ee1770d4 and 10c2254d41, part of T74432.
Now the area and region naming conventions should be less confusing.
Mostly a careful batch rename but had to do few smaller fixes.
Also ran clang-format on affected files.
Both the MS headers and blender headers define the HKEY
which gives all kind of inclusion order issues.
This diff renames all *KEY constants to EVT_*KEY to resolve
this conflict.

The old convention was easy to confuse with ScrArea.
Part of https://developer.blender.org/T74432.
This is mostly a batch rename with some manual fixing. Only single word
variable names are changed, no prefixed/suffixed names.
Brecht van Lommel and Campbell Barton both gave me a green light for
this convention change.
Also ran clan clang format on affected files.
