draw_sprite_flip_ext

COPY/// draw_sprite_flip_ext(sprite,subimg,x,y,xscale,yscale,rot,color,alpha,fliph,flipv)
//
//  Draws a sprite in the same manner as draw_sprite_ext() and
//  can also flip the sprite horizontally and/or vertically.
//  When flipped, the sprite will be drawn within its normal 
//  bounding box rather than being flipped about its origin.
//
//      fliph       true to flip horizontally
//      flipv       true to flip vertically
