Fixed VDB Points support in the Geometry Light node

Fixed a regression from 20.5 where the HDK CMake module's `Houdini` target did not include some libraries required for certain HDK plugin types, such as those involving the OPUI or DM libraries. The `hcustom` utility is also now consistent with this set of libraries.

Fixed a crash that could occur with the %closerthan and %fartherthan auto collections when specifying a target prim that doesn't exist.

Set the Rename Sub Segments param default to '*'. This fixes the meta hand setup in the rigbuilder.

Fixed a crash when doing a pick render pass on a Polygon Primitive with empty geometry

Fix python exception that would occur when deleting the node name of a node whose type is namespaced. Now the node name gets set to the "primary" type name (without namespacing) as intended.

When a python exception occurs during scene evaluation in the APEX Animate viewer state, the exception window will no longer pop up. Instead, an error message will appear in the viewport and the exception will be added to the Log Viewer.

Fixed a crash in the Volume LOP that would occur when it was set to sample a frame range, but the frame range provided was invalid (e.g. 0,0,0).

Fix regression in the reference and referencedby LOP auto-collections which caused them to not find instance proxy prims that they should have matched.

Recipes: Fixes node type validation for recipes when the editable content's node type differs from the asset's node type. This affected objnet assets like hairgen and guidegroom.

Fixed incorrect handling of render product filenames that contained angle brackets (such as "foo<bar>.exr").

Fixed incorrect handling of render product filenames that contained angle brackets (such as "foo<bar>.exr").

Reduce memory overhead when compiling shaders for the viewport

Fixed a bug where XRay primitives aren't drawn properly in some viewport lighting modes

Fixed a bug where visualizers wouldn't draw if the visualizer was set to only allow Primitive attributes

Fix viewport errors rendering curves and using MaterialX materials with curves

Added parameters "Use Upper" and "Use Lower" to the twist tab of the limb component.

The Instancer LOP now has a "Create Prototypes Area" parameter. When disabled, prototypes are linked to directly in their current scenegraph location. This is only relevant when using prototypes from the first input connection.

Fixed handling of deep OpenEXR images for the dsmpixel() VEX function.

Fixed handling of deep OpenEXR images for the dsmpixel() VEX function.

RBD Car Fracture SOP's guide geometry and selection geo now updates properly when a car rig or simulation points are fed into the 4th input.

Fixed preloading libraries for render delegates.

Removed the HoudiniAsset, Inputs and Parameters arrays from the runtime part of the plugin via WITH_EDITORONLY_DATA guards, as their garbage collection at runtime could in some case introduce an unneeded extra cost. (Houdini actors and components do not need to access these at runtime)

• Added support for COP HDA inputs, and COP node path parameter inputs (coppath).
• Fixed a few issues with asset editor in 2d mode.
