Nanosvg assumes that an unspecified stroke width is 1px, whereas the SVG
specification specifies it should be read as 0px. This causes problems
when scaling factors are applied to 0px lines, leading to them being
misinterpeted by our import.
This commit fixes the nanosvg assumption by setting the initial stroke
width to 0 instead of 1px.

This was flagged by coverity but doesn't seem to be an actual issue in
g++/clang. It technically leaves the moved rvalue in a "valid but
undefined state", so it is best to avoid. The single copy into an
lvalue is (I think) cheap
Fixes an issue with `wait_for_tasks()` and adds a lower-overhead
`push_loop` helper. We replace our usage of `parallelize_loop` with
`push_loop` as we didn't use the multi-future vector return and don't
need the extra overhead.
Currently this lives behind the advanced config flag `UseClipper2`.
Enabling this flag will route all Clipper-based calls through the
Clipper2 library instead of the older Clipper. The changes should be
mostly transparent.
Of note, Clipper2 does not utilize the `STRICTLY_SIMPLE` flag because
clipper1 did not actually guarantee a strictly simple polygon.
Currently we ignore this flag but we may decide to run strictly-simple
operations through a second NULL union to simplify the results as much
as possible.
Additionally, the inflation options are slightly different. We cannot
choose the fallback miter. The fallback miter is always square. This
only affects the CHAMFER_ACUTE_CORNERS option in inflate, which does not
appear to be used.
Lastly, we currently utilize the 64-bit integer coordinates for
calculations. This appears to still be faster than 32-bit calculations
in Clipper1 on a modern x86 system. This may not be the case for older
systems, particularly 32-bit systems.
nanodbc was overriding the C++ standard library being used, which would
break builds with clang. Additionally, adding Werror unconditionally in
production code is a bad idea because different compiler versions can
change/add warnings and then break the code.
Allows placing parts from an external database that reference symbols from another loaded library.
Includes:
- nanodbc wrapper
- database schematic library plugin
- basic tests

Thread pools are long-lasting executors that have close to zero overhead
when launching new jobs. This is advantageous over creating new threads
as we can use this for threading smalling jobs and smaller quanta. It
also avoids the heuristics needed to determine the optimal number of
threads to spawn
