Updated Houdini's USD library to match the official USD 23.05 release.

Ported attribute transfer optimizations from Unreal 5.0 to Unreal 4.26 & 4.27

Added Texture Mask Brush HDA. Meant to be used to define custom brushes to be used with the Texture Mask Paint SOP.

Ported Unreal 5.0 optimizations to Unreal 4.26 & 4.27.

Suppress warnings about missing table types for future table types.

Added an Enable toggle to each Target multiparm instance on the Prune LOP.

The Reference LOP has a new mode (controlled by the new Parameter Order parameter) which allows the Reference File and Reference Prim Path parameters to be evaluated once per matching Primitive, rather than evaluating the Reference File first, then evaluating the Primitives parameter once per matching file. This node will also now apply the Pre-Operation to all matching Primitives even if no reference is being added to these primitives.

Fixed bugs where the state of the virtual keyboard in the hotkey manager was incorrect when in a context with no immediate child actions and you couldn't open the assignments window by clicking on a key.

Transforms are now handled differently in mantra and karma CPU. The new method allows for more accurate rotational motion blur and will consume less memory.

Framing the selection in the Channel Editor Graph now considers selected Key Value Handles in addition to selected Time Marks.

Custom directories entries can now be prevented from saving to the user preferences directory by creating an empty jump.prefs.nosave in it.

Fix bug with Bone/Joint Deform SOPs where it may fail to correctly update after cooking an incorrect/bad boneCapture attribute.

Fixed a case where drawing Volumes could hang in the GL viewport when large scaling transforms are applied

An error is now added to the ROP node when a render is interrupted.

Updated Houdini's USD library to fix a performanec issue with drawing instanced prims with unloaded payloads as bounding boxes. The bounding boxes were not being drawn as instances. Also fixed an issue where importing the USD python libraries could raise an exception on Windows if the PATH variable contained a relative path.

HeightField Paint SOP's recache strokes will no longer generate a python exception.

Fixed an issue with the pdg.GraphContext.cook(..) API method throwing an exception when invoked with a pdg.CookOptions instance as its only argument.

The Wire Blend SOP can now be used in compiled networks and has been verbified.

New Bone Deform and Joint Deform SOPs will now be created to deform all attributes marked as transforming by default. To support this workflow, when the Deform Normals toggle is disabled, this will also prevent N from being used if it's specified in the Other Attribs parameter. Note that this may cause N to no longer be deformed if old hip files had this situation.

Fixed minor issues for kma_room_map to make it work with upcoming new SOP room_basis.
