Re-order draw methods to make update-api happy

update-api orders methods alhabetically by name, but when
there's multiple methods with the same name it falls back to
the ordering within the file.

Re-order the methods in canvas.java to match what's already in
current.txt to avoid unnecessary changes.

Also auto-formatted the draw methods as some were mis-indented.

Test: No behavior change, just method re-ordering
