 RS_TYPE_UNSIGNED_5_6_5, RS_TYPE_UNSIGNED_5_5_5_1, RS_TYPE_UNSIGNED_4_4_4_4 are for packed
 graphical data formats and represent vectors with per vector member sizes which are treated
 as a single unit for packing and alignment purposes.

 This enumeration is primarly useful for graphical data.  It provides additional information to

 RS_KIND_USER indicates no special interpretation is expected.

 The RS_KIND_PIXEL_* values are used in conjunction with the standard data types for representing
 texture formats.
