Fixed the casing on the time parameter for the lens_parameters VOP.

Fixed a bug in LPE AOVs where excluding a light with certain LPE tag using `^` metacharacter would erroneously exclude lights with empty LPE tag as well.

Backported fix for handling references to husk procedural graphs with environment variables in the path.

Reduced time it takes to resume from checkpoint when deep images are enabled.

Fixed possible crash when resuming render from checkpoint if deep images and husk's snapshot feature are both enabled.

Fixed a bug in the SOP Import LOP where agents were imported incorrectly if there were unique agent definitions with same value for the 'agentname' attribute.

Houdini, Karma and other applications will no longer print out warnings about OCIO color space rules not matching the image metadata unless the HOUDINI_OCIO_TEXTURE_WARNINGS variable is set. This variable can be used to help diagnose color space issues with textures.

When a USD ROP save operation is set to strip off data from above layer breaks, the layers above the layer break would be removed from the stage, then added back to cook the next frame, then removed again, etc. for each frame. This could incur significant recomposition costs and slow the export. Now the layers above the layer break are stripped off during the save operation without altering the stage and avoiding the recomposition.

Fixed a bug in the Clone Control Panel where double-clicking to choose a LOP clone to render raised a Python exception.

Fixed regressions introduced in 21.0.633 where applying clips in the Animation Catalog and merging APEX Animation Layers would throw python errors
