Camera state in LOPs triggers infinite redraw when viewport is split

• Fixed a crash in the LOP camera state when updating its HUD info panel.

Added "guidegenerators" Python plugins to create the geometry drawn in the viewport for lights and cameras. This allows for more dynamic guides (for example, the guide for lights now respects the cone angle of a spotlight)

Fixed an issue where creating a new camera from the viewport camera could generate scaled values when the stage had metersPerUnit set to values other than 1.0

Fix a regression in 19.5.613 to the parsing of the UsdRenderer.json file that broke the ability to use the Storm render delegate in Houdini.

Fixed a crash when dirtying and recooking consecutive command chain blocks.

Karma XPU now supports OCIO texture lookup to match Karma CPU.

Moved initialization of HUDs by states from construction to entry. Python states can use a new onCreateHUD() handler to explicitly do this, but any changes requested through hou.SceneViewer.hudInfo() during construction of a state will be automatically delayed until the appropriate time.

Fixed a bug where rendering with a custom BSDF with 'sss' label alongside built-in subsurface scatter BSDF would lead to a crash.

Fixed an issue with service client processes timing out during startup, when the service pool size is set to a large (50+) client count.

Fixed a bug in the Lidar Import SOP that omitted point colors in multi-scan E57 files.

Fixed an HQueue bug where setting the `[waitress] -> ignore_logging` key in the hqserver.ini configuration file did not suppress all waitress logging messages.

Fixed an issue where certain light guide geometry wouldn't highlight properly in the viewport when the corresponding prim was selected.

The Configure Primitive LOP can now set the "Apply Draw Mode" metadata on a primitive (so the draw mode can work on prims that are not components or unloaded payloads).

Fixed errors in the detection of time varying stage data in the bounds auto collection. Removed the Frame parameter from Set Extents, and added a toggle to control whether manual bounds are specifying world or local space bounds. Added multisampling parameter to the Loft Payload Info LOP, and the parts of the Configure Primitives LOP that can be meaningfully time sampled (extents, visibility, and card draw mode texture maps).

Fixed a bug where using Mtlx Transform Matrix VOP with Vector 3 signature in a shader would cause the shader to fail to compile.

Fixed potential crashes in the trim, ltrim, and rtrim functions.

Fixed an issue with service client processes timing out during startup, when the service pool size is set to a large (50+) client count.

Fixed a bug in the Lidar Import SOP that omitted point colors in multi-scan E57 files.

Fixed an issue with landscapes being resized incorrectly when not an Unreal-approved size.

Removed World Outliner and Foliage baked types completly as they were previously deprecated.

• Fixed bug that caused incorrect vertex colors/alpha on imported Static Meshes.
• Fixed bug that caused incorrect vertex colors overrides on Static Mesh Components.
