New subject: [PATCH 2/6] gdi32: Change the compute_metrics() location to get more accurate metrics.

11 Feb 2019

Wine-bug: https://bugs.winehq.org/show_bug.cgi?id=46512
Signed-off-by: Byeongsik Jeon bsjeon@hanmail.net
---
GGO_METRICS does not assume a specific GGO format but applies the current
DC aa_flags.
[PATCH 1-6] fixes some problems in bug#46512:
'letter cut off' and 'text layout unstable in runtime'
I'll post the other issues later:
FreeType 'strong' autohinter, v40 FT_LOAD_TARGET_MONO,
ClearType compatable advance width.
