[Okular-devel] Another issue with tiled rendering

[Albert Astals Cid]

Hi Mailson, another issue i found with tiled rendering branch.

In this branch you raised the max zoom level from 400% to 1600% this is all 
fine for the PDF backend that does support tiles, but all the others do not 
and will easily end up hitting the barrier in which we consider the pixmap to 
be too big and don't draw it.

It'd be necessary if we bubble up that information to the ui layer and show 
one of the information bubbles saying "Too much zoom, please reduce"

OTOH maybe it'd be even cooler if the max zoom was calculated with that 
barrier in which we consider the pixmap to be too big and don't draw it and 
thus the user could never reach that situation (or maybe not because a 
variable zoom limit is weird)

What do you guys think?

Cheers,
  Albert
