Height of canvas produced by drawtext varies depending on symbols in
text, so add example for printing separate texts aligned horizontally.
Wording suggested by Lou Logan <l...@lrcd.com>
Signed-off-by: Andrey Utkin <andrey.ut...@pb.com>

Changes in v2:
* Taken the wording of example and description Lou proposed
* Added mention of @var{max_glyph_a} to "Note that..." phrase
(is the markup used for this correct?)
* Slightly edited commit message for clarity of meaning
(dimensions vary -> height varies)
