axis.m: Fix 'axis tight' with pcolor plots. * libinterp/corefcn/graphics.cc(calc_dimensions): Use if/else if tree to avoid unnecessary comparisons once object has been determined to be 3-D. * libinterp/corefcn/graphics.cc(F__calc_dimensions__): Put input validation first. * scripts/plot/axis.m: Check for 2D view (elevation = 90) before setting Z limits.
