Update: now it works even when NPOT textures are not supported, so GeForce 
FX / Radeon 9500 and up should work.

When NPOT textures are absent, I just create a larger POT texture. E.g. if 
your display is 1280x1024 then 2048x1024 texture is used. This wastes some 
memory, but at least it works.
The other way would have been to use rectangle textures, but this turned out 
to be much more difficult than I thought, so it won't be done for now.
