Dropdown in Windows

[sjoshid]

I managed to successfully F up PR #2042. (Patting my back)

This PR adds ability to let dropdowns cross their parent boundary.

Thanks! Just one very minor suggestion.

[sjoshid]

I need to fix the changes I made in set_position().
Please hold off on merging this.

[sjoshid]

^^
This is ready to merge (assuming there are no more code review changes)

[jneem]

Thanks!

[sjoshid]

^ Thank you too.
Im going to pick your brain one last time.
Recently installed linux to understand more about gtk because it always comes up but Im seeing.........bizarre behavior to say the least.
My assumption was subwindow positioning was impl recently in gtk meaning it was working.
Is the assumption wrong?

@sjoshid can you check the x11 backend (cargo run --example subwindow --features x11 --no-default-features)

[jneem]

Thanks, I'll look into those. It's highly likely that some things didn't get properly updated when we changed to relative positions.

[sjoshid]

@maan2003 I cant. :( Im running into build errors one after another. Sorry.

@jneem Thanks.

[sjoshid]

I know Im late....but I fixed build errors (like libclang not found, etc.) for x11.
Happy to report x11 is working as expected (to Windows). The tooltip position is off in sub_window example but other than that it looks good.

[maan2003]

nice :). please create an issue about tooltip positioning with the desktop enviroment version, screenshots, ... I tried fixing positioning but it is hard to fix for all enviroments on linux.

[sjoshid]

Done. #2100

[jneem]

@maan2003 I think I found a little bug with DP scaling and get_position (#2101).
