Reduce surface area of MeshDescriptionProvider/Committer, replace with UE::ToolTarget:: calls where possible. Add new UE::ToolTarget::CommitMeshDescriptionUpdateViaDynamicMesh() function. This is being used for now to avoid potential regressions as UE::ToolTarget::CommitDynamicMeshUpdate will preferentially use DynamicMeshCommitter, and I am not certain it is functionally equivalent in all cases. Add new UE::ToolTarget::CommitDynamicMeshNormalsUpdate(), similar to existing UV version Add new Move-variant of UE::ToolTarget::CommitMeshDescriptionUpdate(), uses new Move-variant of IMeshDescriptionCommitter::CommitMeshDescription. Make existing IMeshDescriptionCommitter::CommitMeshDescription callback interface protected, to prevent usage of this function at public API level (will be removed in future). Tool updates should not change, just using cleaner APIs. EditNormalsTool now uses CommitDynamicMeshNormalsUpdate(), which does go via DynamicMeshCommitter preferentially, where it previously went via MeshDescriptionCommitter. In light testing the results appear equivalent. AttributeEditorTool now operates on MeshDescription copies in various update functions. These are not performance-critical. #rb rinat.abdrashitov #rnx #preflight 61ae45998358693a22c28d1b #ROBOMERGE-AUTHOR: ryan.schmidt #ROBOMERGE-SOURCE: CL 18384350 in //UE5/Release-5.0/... via CL 18384361 #ROBOMERGE-BOT: STARSHIP (Release-Engine-Staging -> Release-Engine-Test) (v896-18170469) [CL 18384373 by ryan schmidt in ue5-release-engine-test branch]
