patch 9.0.1970: win32: high-dpi support can be improved Commit: https://github.com/vim/vim/commit/7086b3e76a81cf87592077d54e0ef46a60006c2c Author: Ken Takata <kentkt@csc.jp> Date: Mon Oct 2 21:26:03 2023 +0200 patch 9.0.1970: win32: high-dpi support can be improved Problem: win32: high-dpi support can be improved Solution: implement WM_GETDPISCALEDSIZE win32: Better support of Per-Monitor V2 High DPI Implement WM_GETDPISCALEDSIZE. It is not so easy to calculate the new size without actually changing the size. So, this returns an approximate size. This doesn't work well when a bitmap font (e.g. FixedSys) is selected, but I think this is acceptable. closes: #11812 closes: #13252 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Ken Takata <kentkt@csc.jp>
