Cleanup
Comment for vertex color was repeated inside the vertex loop creating unnecessary comments.
Fixed: 0 Hair amount error
Improved: exportable hair amount

Hair exported only the view percentage, full amount gets exported now. allowing much higher counts than what could get displayed. also since the lowest count (0) is no longer divided by the view percentage it removes a "division by 0" error.
OBJ export: Dont use the name "Loop" in blenders UI

this is an internal name only.
Fix for error in r4790 index data isn't always required
Fix T34801: bridge tool, internal faces deletion
Internal faces are now correctly deleted and smooth shading is applied.

Fix: matrix operations
Based on report in anonymous forum.
