This commit improves the scaling of some ui widgets when
zooming by making the radius of the rounded corners
dependent on the element's zoom level.
Needed to fix T92278 without padding issues, see D13125.

Somehow, the file from T71329 has an empty curve profile. While that may
be a problem in itself, it's reasonable to avoid asserts or crashes when
loading or drawing such a CurveProfile. This commit just makes sure the
table always has a single vertex, and adds some checks in drawing code.
Passing 4x arguments for the rectangle,
mixed in with round-box radius & color wasn't very readable.
Instead, pass a `rctf` as the first argument to UI box drawing functions.
The new GPU_SHADER_2D_WIDGET_BASE shader allows us to draw
many complex shapes with anti-aliasing.
One thing it can do is draw an opaque rounded rectangle with colors
that differ between its interior and outline.
In order to do the above in a single pass I recently added an "_ex"
version of UI_draw_roundbox that exposes most of that shaders features.
This simplifies interface_draw.c by removing redundancy in the calling
of this shader by using this new uber "_ex" version.

If there was a control point at an extreme position when drawing a curve
profile (in the bottom corner), the fill's trianglulation could fail, giving
a misleading view of the curve. This is because the extra points added to
create a closed shape were exactly on the border of the view.
This commit adds a small margin to those points, so the triangulation
doesn't fail because the line overlaps itself.
Another possible solution is to use a different algorithm to fill
the polygon, such as scanfill, which is used by curve objects.
This seemed simpler, and seems to work fairly robustly.

This patch fixes assert on grid drawing. `for` loops are used instead
of `while` loops to make sure the number of lines is exact. The old
code draws lots of unnecessary lines offscreen. This bug is fixed as
well. See the patch for a comparison without a scissor test.

Under the hood the CurveProfile widget (used for bevel custom profiles)
uses a bezier curve, but right now though it only supports two of the
bezier curve handle types, vector and auto. This patch adds support for
free handles and adds all of the logic for editing them.
This is the first step to the ability to import and export curve objects
in the widget.
There's some code cleanup in curveprofile.c. Movement for handles and
control points is abstracted to functions there rather than happening
in interface_handlers.c.
An "Apply Preset" button is also added, which solves a confusing issue
where you apply a preset, then change the number of samples and the
preset doesn't change. The button makes it clear that the preset needs
to be reapplied.

This means all the antiailasing is done inside the fragment shader.
We use a Signed Distance Field to draw the 2D rounded boxes. This ensure
the best quality for AA.
This reduce the averge Batch for widget to 16 verts instead of ~600 and
reduce overshading a lot.
Theme Emboss alpha and tria alpha needs to be changed after this refactor.
The shadow drawing is left unchanged and still use geometry.

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.
Extend options are currently stored per curve. This was not clearly
communicated to the user and they expected this to be a setting per
CurveMapping.
This change will move the option from `Curve` to `CurveMapping`. In
order to support this the API had to be changed.
BPY: CurveMap.evaluate is also moved to CurveMapping.evaluate what
breaks Python API. Cycles has been updated but other add-ons have
not. After release of 2.81 we can merge this to master and adapt
the add-ons.
