[PATCH v2 0/2] MR2302: gdiplus: Use FILE_SHARE_READ in GdipPrivateAddFontFile().

[w-flo (＠w-flo)]

ZusiDisplay sometimes loads the same font file into two different
PrivateFontCollections using two threads, so there is a race condition
when the file is opened without the FILE_SHARE_READ sharing mode. The
second call to GdipPrivateAddFontFile() might fail if the first one
hasn't closed the file handle yet.
