_glPointSize: specify the diameter of rasterized points

  SUB _glPointSize (BYVAL size AS SINGLE)
  void '''_glPointSize'''(GLfloat ''size'');

size

Specifies the diameter of rasterized points. The initial value is 1.

_glPointSize specifies the rasterized diameter of points. If point size mode is disabled (see _glEnable with parameter _GL_PROGRAM_POINT_SIZE), this value will be used to rasterize points. Otherwise, the value written to the shading language built-in variable :Template:Code will be used.

The point size specified by _glPointSize is always returned when _GL_POINT_SIZE is queried. Clamping and rounding for points have no effect on the specified value.

_GL_INVALID_VALUE is generated if size is less than or equal to 0.
