Re: size hints and tiling window managers

[Jan Djärv]

Hello.

Min_height/width is not that important, they dont have to be a multiple of 
frame_height/width.
Not setting the height/width_inc would mean that Emacs resizes a pixel at a 
time, not a row/column at the time.  And those window managers that provide 
resize feedback would be showing width x height as pixels instead of columns x 
rows.  That would be a bigger bug IMHO, than having some pixels off at the 
edges.
