Merge the PR's upstream update without the assembly view painter block

The update merged the same upstream commits this branch already carries. Its
GLCanvas3D resolution kept the assembly view painter block after the ghost
render, which section view removed along with the members it calls, so that
tree does not build. This merge keeps the removal; nothing else differs.
