* @description:
* This function analyzes a glyph outline and tries to compute its
* fill orientation (see @FT_Orientation). This is done by computing
* the direction of each global horizontal and/or vertical extrema
* within the outline.
* fill orientation (see @FT_Orientation). This is done by integrating
* the total area covered by the outline. The positive integral
* corresponds to the clockwise orientation and @FT_ORIENTATION_POSTSCRIPT
* is returned. The negative integral corresponds to the counter-clockwise
* orientation and @FT_ORIENTATION_TRUETYPE is returned.
*
* Note that this will return @FT_ORIENTATION_TRUETYPE for empty
* outlines.
