Bug 1412427 part 4: Indent under-indented MPL boilerplate comments by 1 space, for consistency & alignment. (whitespace-only) r=jrmuizel

This patch was automatically generated. I found the files to be fixed in this
patch with the following command:
grep -r "^\* This Source Code" gfx

...and then I modified each of these files with the following script
(where $1 is the filename to be modified):
###
line1="\* This Source Code Form is subject to the terms of the Mozilla Public"
line2="\* License, v\. 2\.0\. If a copy of the MPL was not distributed with this"
line3="\* file, You can obtain one at http://mozilla\.org/MPL/2\.0/\. \*/"

# Insert 1 space at beginning:
sed -i s%"^$line1"%" $line1"% $1
sed -i s%"^$line2"%" $line2"% $1
sed -i s%"^$line3"%" $line3"% $1
###
