   typedef struct {
                   float x_angle;
                   float y_angle;
                   float z_angle;
   } Xint3DRotation;

   typedef struct {
                   float x_scale;
                   float y_scale;
                   float z_scale;
   } Xint3DScale;

Resource Value	Description
XintSIMPLEX_ROMAN (default)	Use a simplex stroke font.
XintCOMPLEX_ROMAN	Use a complex stroke font.
XintTRIPLEX_ROMAN	Use a triplex stroke font.
XintCOMPLEX_GREEK	Use a complex greek stroke font.

Resource Value	Description
XintSIMPLEX_ROMAN	Use a simplex stroke font.
XintCOMPLEX_ROMAN (default)	Use a complex stroke font.
XintTRIPLEX_ROMAN	Use a triplex stroke font.
XintCOMPLEX_GREEK	Use a complex greek stroke font.

Resource Value	Description
XintXY_PLANE	Draw grid lines in the XY plane.
XintXZ_PLANE	Draw grid lines in the XZ plane.
XintYZ_PLANE	Draw grid lines in the YZ plane.

For example, to have all X grid lines drawn, specify XintXY_PLANE+XintXZ_PLANE for resource XmNxGridLines.

These resources are specified as a pointer to a data structure of type XintIncrements which takes the following form:

   typedef struct {
                   float major_increment;
                   float minor_increment;
   } XintIncrements;

   typedef struct {
                   float minimum;
                   float maximum;
   } XintLimits;
