Hi,
you could 'draw_quad' the full map on a not visible bitmap at its pixel to pixel scale and use it as source map in a shader over a view or a 'bmap_process' inside a loop. It would let you use any scale on the visible bitmap with the proper samples. I am afraid anisotropic filter does not work on texture samples but linear interpolation is enough, I guess. It is pretty easy to develop. I can help.

Salud!
