[PATCH 0/2] MR7247: user32: Use SYSTEM_FONT if given font is not installed.

[Akihiro Sagawa (＠sgwaki)]

We also check the pixel size to avoid the problem of using the bitmap font when the specified system font, such as MS UI Gothic, is not available.

[PATCH 2/2] user32: Use SYSTEM_FONT if given font is not installed.

[Marvin]

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

The full results can be found at:
