using mface->flag for both.
Also found that the cdDM_drawMappedFaces and cdDM_drawFacesTex_common could get normals mixed up when rendering hidden faces. because hidden/invisible faces used continue without advancing to the next normal.
off_export - minor changes
uv_archimap - cleanup. slightly slower but less duplicate code
uv_from_adjacent - nothing
BPY_menus - renamed py slot UvCalculation to UVCalculation to be consistant
Use this script in face select mode.
Note- If you make new faces between faces that are alredy UV mapped there is currently no way to say- map from others... this script does exactly that. and can save a lot of time manually moving and welding UV coords one by one.
Its realy usefull for mapping after a scanfill too.
