ALLEGRO_PRIM_TYPE - Allegro 5 API

       Enumerates the types of primitives this addon can draw.

       • ALLEGRO_PRIM_POINT_LIST - A list of points, each vertex defines a point

       • ALLEGRO_PRIM_LINE_LIST - A list of lines, sequential pairs of vertices define disjointed lines

       • ALLEGRO_PRIM_LINE_STRIP - A strip of lines, sequential vertices define a strip of lines

       • ALLEGRO_PRIM_LINE_LOOP  - Like a line strip, except at the end the first and the last vertices are also
         connected by a line

       • ALLEGRO_PRIM_TRIANGLE_LIST - A list of triangles, sequential triplets  of  vertices  define  disjointed
         triangles

       • ALLEGRO_PRIM_TRIANGLE_STRIP - A strip of triangles, sequential vertices define a strip of triangles

       • ALLEGRO_PRIM_TRIANGLE_FAN - A fan of triangles, all triangles share the first vertex
