Bug Fixes in Office
Do not overwrite the embedded pattern when it is the same
Well, doing the same work again and again is not a good idea :)
Now we just check whether the two md5 sums coincide and whether
there is at least some data present in the embedded pattern field.
If it is true, just skip saving. This fixes the Shift-gesture brush
scaling for some brush presents.
Thank Mifth for reporting this bug!
