Re: widget size independant to screen resolution

The only problem with that is that there must be an anti-aliasing for everything that exists on the screen. Also there must be some kind of smart filtering for images (there is a cool algorithm with the same name. I've seen the descrption for that in russian (somewhere on www.gamedev.ru). But i don't know if there is in english.)

BTW, where must this feature be located? I think somewhere in themes implementation, so not every theme can support it. For example themes with raster widgets can't fully support it.

Best whishes, Dmitry.
