faces
Controls the visual representation of the lattice faces. In 
wired 
mode, the lattice faces are represented by wired lines connecting the 
vertices.  In 
solid mode, the lattice faces are represented by 
solid polygons, that users can see from the outside or from the inside.
When the selected 
type is 
rhombus or 
sphere, 
the cell must be represented in 
wired mode, otherwise the 
actual lattice would be hidden by the filtering volume. When
type is 
projection, faces cannot be represented.
The cell object must always have a visual representation, so
at least one of the lattice components, 
faces, 
nodes
and 
borders must be visible.
Example: <cell ... faces="no"/> (default)
Allowed values: yes, no (optional)
nodes
Controls whether the lattice nodes are visible or not. When 
type is 
projection, nodes cannot be represented.
The cell object must always have a visual representation, so
at least one of the lattice components, 
faces, 
nodes
and 
borders must be visible.
Example: <cell ... nodes="yes"/> (default)
Allowed values: yes, no (optional)
borders
Controls the visual representation of the cell borders. When 
borders
is 
none, no borders are represented in any cell representation. 
When 
borders is 
edges, only the outer line contours are shown. 
The boundaries between cells are hidden, as long as they are in the same 
plane, independently of the lattice parameters. When 
borders is 
faces, all lines are shown, except those inside the volume 
representation, making it easier to see the cell contents. Selecting 
the option 
all, all border lines become visible, including those 
inside the cell. 
The 
faces and 
all options are disabled when 
type is
set to 
rhombus or 
sphere filtering modes. The 
all option 
is disabled when 
faces is set to 
yes, because in solid mode the 
inner borders cannot be seen from the outside and make it very difficult to 
analyze something from the inside. When 
type is 
projection, the 
borders option is always 
edges, meaning the projection circumpherence.
  
The cell object must always have a visual representation, so
at least one of the lattice components, 
faces, 
nodes
and 
borders must be visible.
Example: <cell ... borders="all"/> (default)
Allowed values: all, faces, edges, none (optional)
red, green, blue
Set the cell color, between black (0.0, 0.0, 0.0) and white (1.0, 1.0, 1.0). 
When the cell is shown in wired mode, this color is used to render the cell 
lattice framework. When the cell is shown in solid mode, faces are rendered 
using this color, and wired boundaries are rendered using the current layer 
background color.
Example: <cell ... red="1.0" green="1.0" blue="1.0"/> (default)
(defined in GAMGI_MESA_CELL_R, GAMGI_MESA_CELL_G
and GAMGI_MESA_CELL_B)
Allowed values: 0.0 - 1.0 (optional, coupled)
scale
Change the cell size, including its child objects. Cell objects are
scaled around the cell center. The visual representation of an object
is always scaled by its own scale factor multiplied by the scale factor
of all its parent objects until layer, inclusive.
Example: <cell ... scale="1.0"/> (default)
(defined in GAMGI_MESA_SCALE)
Allowed values: positive real (optional)
