Pull Request Overview

This PR implements planar texture alignment support for PBR (Physically Based Rendering) materials, extending the existing alignment functionality that previously only worked with Blinn-Phong materials. The changes enable the planar alignment checkbox to properly function with PBR texture transforms.

Key Changes:

• Added a new overloaded calcAlignedPlanarTE() method that accepts explicit transform parameters for PBR materials
• Modified LLPanelFaceSetAlignedTEFunctor to handle both PBR and Blinn-Phong materials based on user selection
• Updated alignment logic to apply transforms to appropriate PBR texture channels (individual or all channels when "Complete material" is selected)

@akleshchev thanks for review! ci build was failing, i think the errors are not related to what files i changed. should i resolve those in the other files?

Doesn't look like your fault, but please update from develop to try and resolve it as it runs fine in other PRs.
