Some size - resolution info

[23fx23]

Id love to be able to get few infos like:
Windows screen resolution or contenair/ modules real pixel sizexy.
( cause iml creation, size, pos ect are absolute, but if we deal in a contenair, we only have a 0..1 range. ie id like to spread in regular manner x cellz and fit contenair size if its later changing. Actually i can cheat by doing the reverse, create celkz of sizex and resize contenair according, but would be cool for several other stuff to be able to convert usine 01 position range to 'pixels' ranges when possible
(think global screen firsr would allow few thingz, contenair/ctrl panel would be great, and a way maybe via iml to get any visual module size and pos would be the last ultimate thing. Kind of get_ctrl_posx
Anything doable not to hard?
