[PATCH 0/6] MR6319: winemac: Use window rects to convert window to visible rects.

[Rémi Bernon]

Doing this before https://gitlab.winehq.org/wine/wine/-/merge_requests/6310 as there's other gdi_driver.h changes pending. Will do something similar to winex11 after https://gitlab.winehq.org/wine/wine/-/merge_requests/6286 is merged to avoid conflicts.

The idea is that once we've computed the visible rect, we can compute visible <-> window rect conversions by using the current offsets only. If the decorations need to be changed, and different window/visible offsets, they will only be changed when window position is updated.
