Re: [PATCH v4 0/2] MR1618: gdiplus: improve performance of GdipScaleMatrix

Alex Henrie (@alexhenrie) commented about dlls/gdiplus/matrix.c:

> This comment is unnecessary (and misleading, since there isn't a loop anymore). Also, the Wine project only uses `/* */` comments in C code, not `//` comments. Just delete the comment.
