Extension with optional "face_colors" tag for dotbim file format to allow multicolor elements.
Idea of multicolor elements was introduced by Viktor Kovacs - paireks/dotbim#11
Main repository for dotbim: https://github.com/paireks/dotbim dotbim website: https://dotbim.net/
To color single element with multiple colors add "face_colors" tag inside an element. "face_colors" is a simple list of integers (integers should be between 0-255) organised in that way:
[r1, g1, b1, a1, r2, g2, b2, a2, r3, g3, b3, a3, ... rn, gn, bn, an]
It should match each face of the mesh.
So let's say you have 3 faces inside one mesh, and wanted to color first face (triangle) as red (255,0,0,255), second as skyblue (135,206,235,255), third as white (255,255,255,255). Then you will have:
"face_colors" : [ 255, 0, 0, 255, 135, 206, 235, 255, 255, 255, 255, 255 ]
