It looks like the problem lies in the implementation of
FormatConverter_CopyPixels. According to the MSDN it is legal to pass a NULL
rectangle pointer to this function. In such case the whole bitmap area should
be copied. The existing implementation silently assumes that the rectangle will
never be NULL.

Fixing this function to properly handle NULL rectangles causes the map to be
drawn correctly.

A patch fixing this issue has been submitted to wine-patches.
