Integrate Instant-Meshes 1. Drop windows 32bit support Add windows 64bit support. 2. Remove Script(quickjs) support The current integrated quickjs is a very old version which doesn’t support windows 64bit system. In the future, (TODO)WebAssembly should be integrate as plugin system. 3. Integrate Instant-Meshes Instant-Meshes take less than 1 second on all three platforms. 4. Remove QuadriFlow Current implementation of QuadriFlow is too slow (take about 5 seconds on the example model) to do realtime remeshing.
