Comment(by dustymugs):

 I'm not surprised you went this way for performance. The
 rt_band_mask_get_pixel should really get all the necessary pixel values at
 once and be a wrapper around rt_band_get_pixel and/or
 rt_band_get_pixel_line.

 {{{
 rt_errorstate rt_band_get_pixels(
   rt_band band
   rt_mask mask,
   int x,
   int y,
   double **pixel,
   int **nodata
 )
 }}}

 I don't get the purpose of **extent since rt_mask should have the
 requisite information to describe itself.

 Also, how do you envision the function call at the SQL level?  I ask
 because you'll want to create a ticket for that function call to which we
 can move this discussion.
