Description of Issue

When building against a USD built from the latest dev branch (as of b8bd87c), you get this error:

include/pxr/base/vt/types.h:162:44 error: 'GfHalf' was not declared in this scope

From what I can tell, the root of the problem lies with the the pxr_shared_library / _install_headers CMake macros, which don't properly support installing PUBLIC_HEADERS into subdirectories. As a result, pxr/base/lib/gf/pxrHalf/half.h is NOT installed into pxr/base/gf/pxrHalf/half.h, but into pxr/base/gf/half.h instead, thereby clobbering pxr/base/lib/gf/half.h, which is what defines GfHalf.

Steps to Reproduce

  1. Build USD, then inspect the output include dir's pxr/base/gf/pxrHalf/half.h (or try to build against it)

Also, the headers are "installed" in the build directory correctly (with the pxrHalf subdir) - it's only on install that they lose the pxrHalf subdir...

…AnimationStudios#177)

Reason: We cache geometry for every text prim in _textGeometryCache in USD. In Fusion, when edit sketch and move cursor, the old text prims on the axes will be removed and new prims will be created, but new prim id could be same with prim id which has been used before and its geometry has been cached in textGeometryCache, so the old wrong geometry is found.
Done: Remove geometry cache if the prim is removed.
