Summary

When creating complex shapekey-based facial rigs, it's useful to blend shapekeys, however, Blender doesn't support blending proportionally. This diff adds the feature.

A shapekey-heavy .blend file useful for testing

Changes overview

Proportional editing is tied into the transform engine, so some code from there was moved around to make at least connected-mode PE available to the 'outside world'. Two new files were added to blenlib BLI_pe.h and pe.c.

The factor calculation part of calculatePropRatio from transform_generics.c is now BLI_pe_factor_distance in BLI_pe.h
Connectivity distance calculation (editmesh_set_connectivity_distance from transform_conversions.c is now in bmesh_operators.c and globally visible as BM_calc_connectivity_distance in bmesh_tools.h --- not sure if this is the best place though

The changes in the transform engine code are minimal, calculatePropRatio calls BLI_pe_factor_distance now instead of calculating factors in-place.

Event Timeline

Proportional falloff distance is now propotional to the mesh bbox diagonal size, so the user will have the same results on both large and small meshes (this accounts for worldspace scaling); GPL stuff added to the new files; Minor tweaks
