1) For a while now we've been using a calculated seg count from a given
maxError, and a correction factor to push the radius out so that all
the error is outside the arc/circle. However, the second calculation
(which pre-dates the first) is pretty much just the inverse of the first
(and yields nothing more than maxError back). This is particularly
sub-optimal given the cost of trig functions.
2) There are a lot of old optimizations to reduce segcounts in certain
situations, someting that our error-based calculation compensates for
anyway. (Smaller radii need fewer segments to meet the maxError
condition.) But perhaps more importantly we now surface maxError in the
UI and we don't really want to call it "Max deviation except when it's
not".
3) We were also clamping the segCount twice: once in the calculation
routine and once in most of it's callers. Furthermore, the caller
clamping was inconsistent (both in being done and in the clamping
value). We now clamp only in the calculation routine.
4) There's no reason to use the correction factors in the 3Dviewer;
it's just a visualization and whether the polygonization error is
inside or outside the shape isn't really material.
5) The arc-correction-disabling stuff (used for solder mask layer) was
somewhat fragile in that it depended on the caller to turn it back on
afterwards. It's now only exposed as a RAII object which automatically
cleans up when it goes out of scope.
6) There were also bugs in a couple of the polygonization routines where
we'd accumulate round-off error in adding up the segments and end up with
an overly long last segment (which of course would voilate the error
max). This was the cause of the linked bug and also some issues with vias
that we had fudged in the past with extra clearance.

You can now enable and disable snap to grid when drawing/editing across
all apps. You can also tie snap to grid to the visibility of the grid
to allow rapid enable/disable via grid display.
Since the commit e8b11c911e, the menu tools->external plugins is empty.
This is because on new system, an added submenu is cloned when added. So any update on the object
after Add it as no effect. The menu stay empty.
With this commit the menu filling is made before adding submenu.
Partititioning small polygons causes excessive partitions when we use a
fixed number of cells per side. Partitioning by size keeps the
partition count limited and speeds the calculations.
Also adds an option to not partition the grid for elements (like 3d
raytracing) that do not need it.

All control blocks (if, for, while, etc.) should have a blank line
before the opening statement and after the closing curly brace or
statement so that it is clear where the control block begins and
ends.
Change error displayed when a Library .cpa file is opened (instead of a Layout file)
Add warning if variants exist in original design.
Parse LAYERHEIGHT in LAYER (same thing a MAKE but without the MATERIAL_ID)
Parse PADEXCEPTION in COMPONENT
Add DESIGN as one of the valid UNITS
Loading speed fixed by changing the way CADSTAR_ARCHIVE_PARSER::InsertAttributeAtEnd works (we now have a new attribute in each node to keep track of how many attributes there are). Now loads a 30,000 line file in 10seconds instead of 25 minutes!
code refactoring:
- Renamed CADSTAR_COMMON to CADSTAR_ARCHIVE_COMMON
- Renamed CPA_FILE to CADSTAR_PCB_ARCHIVE_PARSER
- Made CADSTAR_PCB_ARCHIVE_PARSER a derived class of CADSTAR_ARCHIVE_COMMON
- Moved all structures in cadstar_pcb_archive_parser.h/.cpp to be defined inside CADSTAR_PCB_ARCHIVE_PARSER class
