red, green, blue
Set the direction color, between black (0.0, 0.0, 0.0) and white (1.0, 1.0, 1.0).
Example: <direction ... red="0.0" green="1.0" blue="1.0"/> (default)
(defined in GAMGI_MESA_DIRECTION_R, GAMGI_MESA_DIRECTION_G
and GAMGI_MESA_DIRECTION_B)
Allowed values: 0.0 - 1.0 (optional, coupled)
scale
Change the direction size, including its child objects. Direction objects are
scaled around the direction 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.
An error is shown when direction
type is
pole or
trace
(stereographic projection) or when
autonomy is
no (direction
cannot scale independently of its parent).
Example: <direction ... scale="1.0"/> (default)
(defined in GAMGI_MESA_SCALE)
Allowed values: positive real (optional)
