Describe the bug

kivy/kivy/lib/ddsfile.py

Lines 312 to 314 in c0d4894

	with open(filename, 'wb') as fd:
	fd.write('DDS ')
	fd.write(pack('I' * 31, *header))

At line 313, writing string is not allowed because the file is opened as binary format.
It should be fixed to b'DDS '.

Thank you.

Oh, I just now saw the comment Kivy does not provide any support for it.
I'm sorry to report false alarm.
