the commits in this pull request fix two posible memory leaks in the Bitmap_Blur() functions of genbitmap.cpp and w3texlib/genbitmap.cpp
the problem with the original files was that 'qq' was initialized to heap memory but never freed before returning from the function when 'order' is 0.
to counter this i've moved the allocation of the pointer below the problematic 'if' statement which should be reasonably safe since it didn't get used before anyways.
