yes
i would suggest that if a disagreement on types remain that people move
the discussion to a thread dedicated to the type of what the disagrement is
abouzt like width/height.
Its not specific to this patch. This should avoid the frustration, as
only once the disagreement is resolved would then someone reply here with
what type it should be.

If you drop bombs on a foreign country and kill a hundred thousand
innocent people, expect your government to call the consequence
"unprovoked inhuman terrorist attacks" and use it to justify dropping
more bombs and killing more people. The technology changed, the idea is old.
