Change Details

This patch adds edge selection support for UV editing (refer T76545). Developed as a part of GSoC 2021 project - UV Editor Improvements. Previously, edge selection simply selected vertices, which resulted in other edges between selected vertices to be also selected. Selections in the UV editor always flushed down to vertices and this caused multiple issues such as T76343, T78757 and T26676. This patch fixes this by adding edge selection support for all UV operators and flushing selections between vertices and edges. Changing UV select modes is now done using a separate operator, which also handles select mode flushing and undo for UV select modes. Drawing of selected UV edges is also updated to match the edit-mesh display in the 3D viewport. Notes on technical changes made in this patch: * Restored the MLOOPUV_EDGESEL flag (removed in rB9fa29fe7652a). * Added support for flushing selection between vertices and edges. * Added edge support for UV selection checks. * Restored the BMLoopUV.select_edge boolean in the Python API. * New operator to handle updating UV select modes and flushing. TODOs added with this patch: * Edge support for shortest path operator (currently uses vertex path logic). * Change default theme color instead of reducing contrast with edge-select. * Proper UV element selections for Reveal Hidden operator.
