So, two things :
1) About my confuse sentence: Most of the time, you can easily build an application that does not care about the real screen size. OSD functions, for instance, use percentage of the screen for positions and sizes. Same for GUI, ...
Then it's not a trouble to allow the user to resize the window.
My question was: what makes your application "unresizable", and can you fix this ?
2) My turn to not understand
Do you mean that st is OK to apply the change for
unresizable windows ? (your IRC log seems to show that st talks about
resizable windows, that's why I'm confused). By the way, I had a quick look about this feature yesterday, and I can easily add this for Linux, and probably win32 (still have to check AdjustWindowRect() styles for this one), so if st is OK, we can do this quiet quickly.
warning edit: all this was wrote before st's post
Aspect ratio is another point (that Raydium can't deal with, actually)
