Fixed mac compile error in nanosvg
don't test stuff in aws
value/Worker: Fix for Mac

Our recent Windows fix broke other platforms.
python/enum.h: Dodge a windows compiler bug

Previously, we'd fail for EXPORT = OTHER_NO_EXPORT.
Merge branch 'master' of github.com:otherlab/core
utility/process: Add cpu_times and max_memory_usage, and port to Windows

Pass args to sqr and cube as const&
Fix windows compile

In particular, revert removal of casts from casting Vector constructors.
I took these out to save a copy in the cast of large, expensive objects,
but the explicit casts are necessary to avoid warnings.
remove temp smooth code and the gmm include it brought with it
Remove tabs from nanosvg
svg/nanosvg: Add arc support

Arcs are converted into series of cubic Bezier curves, each covering
at most 90 degrees.  We now have nanosvg unit tests (actually regression
tests), which also caught a bug in full circle handling.
get rid of unnecessary comment
added proper has_to/from_python for tuples
added has_to/from_python for void
Merge remote-tracking branch 'refs/remotes/origin/A3DP/master'
Make segment distance routines *mostly* robust

Segment-point, segment-segment, line-point, and line-line distance
computation should be now be as numerically stable as possible,
including optional computation of weights and normals (normalized
vectors between closest points).  The current segment-segment normal
computation is slightly flawed, and occasionally violates the KKT
conditions (see https://github.com/otherlab/core/issues/42).
BoxVector: Fix typo in comment, and expand
Changed project by removing static Debug and Release configurations and renaming DebugDLL and ReleaseDLL to Debug and Release, correspondingly; also eliminated the use of OTHER and switched to SolutionDir
