Backport for r517701 - Removed shiboken6 import from Stage Manager view. This was left out from an earlier version with a bug fix

Fixed jitter in the viewport's FPS display during realtime playback, which made it falsely appear as if it was unable to maintain realtime playback.

Fixed a bug where some textures wouldn't load properly if they were being re-loaded a second time

Added support for multiple target shapes per muscle in the Otis Muscle and Tissue Configure SOP.

Added Shape Attribute parameter to Muscle Mirror SOP as well as ensuring that tpose attribute is mirrored instead of created from mirrored P values.

Improvements to FEM Deform for Otis compatibility:

• Added a toggle to ignore stiffness attributes.
• Added a piece parameter for piecewise deformation.

Fixed an issue with Python-based PDG nods failing to generate work items when a parameter error occurs, even if the pdg.ExpressionError exception is caught during parameter evaluation.

Add a line to the HUD Info in the APEX Animate state to show the hotkeys for displaying the selection set HUD panels.

Removed the global state check in hou.ui.setHideAllMinimizedStowbars(). We can't assume that all the stow bars have the global state since new stowbars aren't affected by the global state on creation.

Recompute affected point normals on the Smooth SOP will now properly only recompute the affected point normals.

Fix a bug where sprites would not render correctly when the gl_spritetex point attribute was set to a valid path.

Scene Import now properly handles `material_override` SOP data for MaterialX materials (as well as the Principled Shader)

Fixed a bug where floating panels wouldn't properly resize and would cause other issues when enabling fullscreen mode

Fixed a bug where outlines wouldn't be drawn in the LOPs viewport, if rendering with a delegate that provides OpenGL Prim ID textures

Fixed an issue where exporting videos with the AMF video encoders would result in a cryptic error message if the width was not evenly divisible by 2.

Fix a bug in Guide Groom's barborient update code where vertex indices weren't converted to point indices prior to accessing point attributes.

Fixed a bug where Work Lights/Scene Lights buttons were unselected when LMB-hold triggerd the RMB menu.

The Image ROP can now write .tx files.

Fixed APEX Scene Add Animation to work with an empty character name.

Fixed a crash in the Copernicus network editor when undoing the deletion of a node that previously had its 3D Output flag set.

Fixed an issue where Shift+wheel scroll in input field resulted in a small non-zero value.
