The GL context lock needs to be shared across kifaces. Otherwise, we
can end up blocking the lock from one kiface. Unfortunately, I can't
find the issue in GitLab right now for where the footprint viewer shows
a blank screen after opening too many contexts. But that's what this
fixes.
Having thread pool as its own singleton in the library meant that each
kiface had its own threadpool, leading to many multiples of the threads
being started. Placing a singleton class in PGM_BASE ensures that all
kifaces use the same thread pool.
The singleton class can be extended to provide single instance
guarantee for any element across kifaces
Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
This means that an early return or an exception between
a manual Push/Pop (or an omission of the Pop) cannot
corrupt the layer stack.
It also means the GAL doesn't have to maintain its own
stack (with the in-scope GAL_SCOPED_ATTRS taking that role).
Reomve the Push/PopDepth functions, as they're only ever
used in pairs, and doing it manually needs more care.

Add dedicated UI rendering layers
Switch to screen-space rendering to avoid blurriness

ordering to be broken when using Scale
Fix some issues with VIEW_GROUP layer ordering
Removes old defines and work arounds for earlier wx versions and adds a
CMake requirement to use at least 3.2 (or the minimum matching wxPython
version)
Also fixes a bug where we didn't triangulate at all when the char
count didn't warrant the likely overhead of spinning up a
thread_pool.
And fix another bug where EDA_TEXT::GetRenderCache() wasn't using
the given font.
Also reverts using the cache for drawing-sheet text. The text
items are created from scratch from the data items each time
they're drawn, so there's never an existing cache to make use of.
Instead, we now check that the item is in the view, using a very
approximate bounding box generator (because even generating a
real bounding box shows up large in profiles).
And, lastly, fixes a bug where EndPos was never considered in
DS_DATA_ITEM::IsInsidePage().

1) Don't fracture font glyphs when generating them; we're going
to fracture during triangulation anyway.
2) Don't check for self-intersection when deciding to fracture.
It costs nearly as much as the fracture does.
3) Cache drawing sheet text.
4) Use the current font when checking for cache validity.
5) Parallelize glyph triangulation.
6) Don't invalidate bounding box caches when offset by {0,0}
7) Use the glyph cache when generating text effective shape.
8) Short-circuit NormalizeJustification() if its center/center.
9) Don't triangulate for GuessSelectionCandidates()
10) Avoid sqrt whenever possible.
11) Pre-allocate bezier and SHAPE_LINE_CHAIN buffers.

Since the format has been changed to RGBA8, default (UN)PACK_ALIGNMENT = 4
works correctly, so the texture width padding to 4 is not needed anymore.
