Franck Bui-Huu 024cd7e088 [PATCH] softcursor.c: avoid unaligned accesses
Fix some possible unaligned accesses when accessing fields of 'image'
pointer.  Indeed this pointer was obtained by allocating a block of memory
that embeds a temporary array plus an image structure.  The temporary
buffer was located at the start of the allocated block and depending on its
size, the image structure which comes right after can be unaligned.

For example when using mini fonts (4x6) (cursor's width is 4 and its height
is 6) the temporary buf size is 6 bytes.

Therefore this patch moves the image structure to the start of the block
and moves the temporary buffer right after.  It makes 'image' pointer
always aligned and since the tempo buf is a buffer of char, it's always
correctly aligned as well.

It also fixes the file header alignement.
