al_draw_filled_polygon - Allegro 5 API
void al_draw_filled_polygon(const float *vertices, int vertex_count,
Draw a filled, simple polygon. Simple means it does not have to be convex but
must not be self-overlapping.
- vertices - Interleaved array of (x, y) vertex coordinates
- vertex_count - Number of vertices in the array
- color - Color of the filled polygon
When the y-axis is facing downwards (the usual), the coordinates
must be ordered anti-clockwise.
