The main issue in an implementation of these functions is the need to constantly edit the vertex array and subsequently update the face and edge arrays.
This change adds RNA access to tesselated face UVs and colors (MTFACE and MCOL), primarily for use by plugin renderers (e.g. cycles). The RNA mesh properties to get to these are prefixed with "tessface_" and additionally the help text states that these are for renderers, to try not to confuse existing mesh editing tool scripts into thinking they could just start using these values.
by Gaia Clary.
Rationale: the name was confusing and not always used consistently, and this
map itself is not something that can be layered, rather the map can be used
as texture coordinates in some layered setup.
The original intent was to indicate this contained more than just UV's, but
the game engine settings have already been moved out, and apparently users
didn't really get this from the name anyway.

Additional changes:
* source/blender/makesrna/intern/rna_linestyle.c: Fixed white
space issues that generated a number of compiler errors. The
problem was that two string literals for enumerating MA_RAMP_SOFT
and MA_RAMP_LINEAR contained a space. The string literals are
supposed to represent a valid C identifier because of their use
for automatic code generation.
* Stroke transparency has been temporarily disabled due to a
functionality conflict with some merged changes. A fix of this
issue is planned.
New "face marks" and "edge marks" have been introduced in mesh data
blocks. In the edit mode of a mesh object, face marks can be put
to selected faces by choosing Mesh >> Faces >> Mark Freestyle Face
from the menu of a 3D View window or Ctrl-F >> Mark Freestyle Face
from the context menu. Similarly, edge marks can be put to selected
edges by Mesh >> Edges >> Mark Freestyle Edge or Ctrl-E >> Mark
Freestyle Edge. These marks should work fine with the Subdivision
surface modifier.
Moreover, two new conditions for feature edge selection have been
added to the Parameter Editor mode as described below:
1. The Selection by Edge Types option has now the new Edge Mark type,
which can be used to (de)select feature edges having edge marks.
This option can be used to add to (or remove from) the view map
arbitrary edges of mesh objects.
2. Selection by Face Marks option has been newly introduced, in which
face marks are used for feature edge selection in two ways. One
option is called "One Face" which is to (de)select feature edges if
one of faces on the left and right of each feature edge has a face
mark. The other option is "Both Faces" to (de)select feature edges
if both faces on the left and right have a face mark.
