> Kimmo, do you recall what was the actual reason of switching?

Kimmo, ping! :) I'm curious to hear your answer!

I made a statistics on loaded image dimensions and I classify them into some groups:

x,y,z := pixels

 (x)    (y)      (x*y) count(x*y)
   2      2          4        553
   4      4         16         22 (4 < z <= 16)
   8      8         64         74 (16 < z <= 64)
  16     16        256        293 ...
  32     32       1024        249
  64     64       4096        596
 128    128      16384       1032
 256    256      65536       1080
 512    512     262144        297
1024   1024    1048576         89
2048   2048    4194304          7
3072   3072    9437184          0
4096   4096   16777216          0

In the case of x*y < 4px there are 125 0*0px  and 394 1*1px images.
