D14784: [scenes/opengl] Fix overlaps in shadow texture atlas

zzag added a comment.


  Ping.
  
  As I said earlier, I think we shouldn't stretch tiles.
  
  If we have to stretch corner tiles, what about left/top/right/bottom tiles? Should we stretch them to match corner tiles?
  
  - if so, what about desktop themes with rounded dialog corners? We'll distort top/right/bottom/left tiles(even though that's hard to notice)
  
  - if not, why then only corner tiles have to be stretched?
  
  In this case, the best what we can do is nothing.
  
  If there is texture bleeding during sliding of popups, that's fault of a desktop theme, not ours.
