draw_sprite_halfpixel

/// draw_sprite_halfpixel(sprite, subimg, x, y, xscale, yscale, rot, color, alpha)
//
//  Draws a sprite transformed about the center of its origin pixel
//  instead of the top-left corner. This can be useful when you require
//  a sprite to maintain the on-screen position of its origin pixel as it
//  is scaled and rotated. Otherwise works the same as draw_sprite_ext().
//
//      sprite      sprite index, real
