Bug Fixes

• Fix Polybrush errors when working with pb 2.6
• Don't specify isFallback in CustomEditor implementations since they are not actually fallback editors.
• Don't rely on loaded assembly names matching the expected ProBuilderEditor assembly name when reflecting types and methods. Fixes null reference when assembly names are changed somewhere in the pipeline.
• Don't bother testing that shader references match when looking for shader metadata since instance ids are so fickle in the first place

Polybrush 0.9.7-preview.0

Features

• Significantly improve perfomance in all modes for high vertex count meshes.

• Improve performance of shared edge triangle lookups, fixing lengthy lags when mousing over high vertex count meshes in paint and texture modes.
• When blending multiple brushes in texture mode use the max weight instead of summing.
• Add information about setting shader paths to Hidden in Shaderforge instructions.
• In vertex sculpting modes iterate per-common index instead of per-vertex, improving brush application performance and minimizing chances of splitting a common vertex by accident.
• Minor cleanup of enum types (make sure they're namespaced & remove unused includes).
• Fix bug where script reloads would null-ify texture mode brush color and not properly reset it.
• Fix errors in brush event logic that caused OnBrushEnter/Move/Exit to be called at incorrect times with invalid targets, resulting in crashes when editing prefabs with multiple meshes with different shaders
• Fix undo throwing errors when splat_cache is null.
• Clamp radius max value to min+.001 to avoid crashes when scrolling radius shortcut with equal min/max values.
• Fix uv3/4 not applying or applying to incorrect mesh channels in ProBuilder (requires update to ProBuilder 2.5.1).
• Fix null errors when sculpting pb_Object meshes caused by FinalizeAndResetHovering iterating the same object multiple times.

Changes

• Set default brush settings radius max to 5.
• When blending multiple brush effects use lighten blending mode instead of additive.
• Shorten ShaderForge source file suffix to "_SfSrc" (but keep compatibility for older "_SfTexBlendSrc").
