Francesco Manzali 17b24e45e8 Fix prompt matrix #rows/#cols when using hires
- images.draw_prompt_matrix() should be called with the final width/height
  of the generated images, after upscaling.
  Otherwise, the number of rows/cols computed in images.draw_grid_annotations
  will increase by the upscaling factor.
- Round the number of cols/rows in images.draw_grid_annotations, since
  the final images width may be a bit less than the required
