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.

Improved animation graph editor workflow.

• linear(), ease(), easein(), and easeout() functions nowshow slope and acceleration handles.
• Dragging these handles or otherwise altering their values willchange the segment into a bezier() function, allowing for finer control.
• For consistency, if your default function is cubic(), it willonly show the slope handles (no acceleration handles) and will transform into a cubic() instead.
• Reminder: the default function can be changed in Edit > Preferences > Animation.

Other changes:

• Removed bezier-linear(), bezier-ease(), bezier-easein(), and bezier-easeout() as theywere obscure and are made redundant by the above changes.
• Fixed an error where "Set Selected Slopes to Linear" in the right click menu could causethe slopes to be NaN.
• Minor performance improvements.

Fix a case where curves were not updating their visibility properly when the 3D hidden primitive group changed.

Unpacking USD and Alembic primitives to SOP geometry now sets the correct default attribute values for standard attributes such as Cd and Alpha.

Replaced the default generated copy constructor and assignment operator on GA_PrimitiveTypeMask with ones that work correctly.

Fixed a bug with the Geometry Import TOP dirtying all work items after a recook, instead of partially dirtying the subset of work items with modifications.

Fixed a bug in the HQueue Client where it continued to output log messages to the hqnode.log file instead of stdout when executed in non-daemon mode.

Fixed a macOS-only bug where the 'houdini' command failed to recognize the -apprentice and -indie arguments for checking out a specific license type.

In Karma Subnet Networ, a Tab > Karma Ramp Parameter creates a Ramp VOP (which promotes the ramp UI) that gets translated to 'kma_ramp' shader prim.
