PointCloud: Initial rendering support for Workbench

Also includes outline overlays. Removes the temp overlay drawing We make the geometry follow camera like billboards this uses less geometry. Currently we use half octahedron for now. Goal would be to use icospheres. This patch also optimize the case when pointcloud has uniform radius. However we should premultiply the radius prop by the default radius beforehand to avoid a multiplication on CPU. Differential Revision: https://developer.blender.org/D8301
PointCloud: Change visualization to use octahedron

   * ninja:         Use ninja build tool for faster builds.
-   * ccache:        Use ccache for faster rebuilds.

   Note: passing the argument 'BUILD_DIR=path' when calling make will override the default build dir.

Clément Foucault	e8f8c13d4b	PointCloud: Initial rendering support for Workbench Also includes outline overlays. Removes the temp overlay drawing We make the geometry follow camera like billboards this uses less geometry. Currently we use half octahedron for now. Goal would be to use icospheres. This patch also optimize the case when pointcloud has uniform radius. However we should premultiply the radius prop by the default radius beforehand to avoid a multiplication on CPU.
