rotate_max
Defines the range of angle values [
-rotate_max, 
+rotate_max]
accepted by the ruler (in the tools menu) to rotate objects. Clicking 
on the ruler extreme left, the object is rotated by 
-rotate_max.
Clicking on the ruler extreme right, the object is rotated by 
+rotate_max. 
rotate_max must be positive.
Example: <window rotate_max="30.0"/> (default)
(defined in GAMGI_GTK_ROTATE_MAX)
Allowed values: real > 0 (optional)
rotate_step
 
The rotation angle applied to the object when clicking on the 
ruler (in the tools menu) increases from the extreme left to
the extreme right (from 
-rotate_max to 
+rotate_max) 
in a step by step way. The width of each step, starting from the 
center to the extremes, is controlled by 
rotate_step.
For example, when 
rotate_step is set to 
rotate_max, 
only two angles are recognized: 
-rotate_max on the left 
(negative) side and 
+rotate_max on the right (positive) 
side of the ruler. When 
rotate_step is 0, the angle 
changes continuously from one extreme to the other.
rotate_step cannot exceed 
rotate_max,
otherwise the extreme values would never be reached
(the central value is always 0).
  
Example: <window rotate_step="0.0"/> (default)
(defined in GAMGI_GTK_ROTATE_STEP)
Allowed values: [0, rotate_max] (optional)
move_max
Defines the range of length values [
-move_max, 
+move_max]
accepted by the ruler (in the tools menu) to move objects. Clicking 
on the ruler extreme left, the object is moved by 
-move_max. 
Clicking on the ruler extreme right, the object is moved by 
+move_max. 
move_max must be positive. 
Example: <window move_max="10.0"/> (default)
(defined in GAMGI_GTK_MOVE_MAX)
Allowed values: real > 0 (optional)
move_step
The translation length applied to the object when clicking on 
the ruler (in the tools menu) increases from the extreme left 
to the extreme right (from 
-move_max to 
+move_max) 
in a step by step way. The width of each step, starting from 
the center to the extremes, is controlled by 
move_step.
For example, when 
move_step is set to 
move_max, 
only two lengths are recognized: 
-move_max on the left 
(negative) side and 
+move_max on the right (positive) 
side of the ruler. When 
move_step is 0, the length 
changes continuously from one extreme to the other.
move_step cannot exceed 
move_max,
otherwise the extreme values would never be reached
(the central value is always 0).
Example: <window move_step="0.0"/> (default)
(defined in GAMGI_GTK_MOVE_STEP)
Allowed values: [0, move_max] (optional)
scale_max
  
Defines the range of factor values [
1 / scale_max, 
scale_max] 
accepted by the ruler (in the tools menu) to scale objects. Clicking on 
the ruler extreme left, the object is scaled by 
1 / scale_max. 
Clicking on the ruler extreme right, the object is scaled by 
scale_max. 
scale_max must be larger than 1.
Example: <window rotate_max="2.0"/> (default)
(defined in GAMGI_GTK_SCALE_MAX)
Allowed values: real > 1 (optional)
scale_step
The scaling factor applied to the object when clicking on
the ruler (in the tools menu) increases from the extreme left
to the extreme right (from 
1 / scale_max to 
scale_max) 
in a step by step way. The width of each step, starting from the 
center to the extremes, is controlled by 
scale_step.
For example, when 
scale_step is equal to 
scale_max - 1, 
only two lengths are recognized: 
1 / scale_max on the left 
side and 
scale_max on the right side of the ruler. When 
scale_step is 0, the angle changes continuously 
from one extreme to the other.
scale_step cannot exceed 
scale_max - 1, otherwise 
the extreme values would never be reached (the central value is 
always 1).
Example: <window rotate_step="0.0"/> (default)
(defined in GAMGI_GTK_SCALE_STEP)
Allowed values: [0, scale_max - 1] (optional)
