If you recall I submitted a separate change proposal for the text baseline
which caused the reopening of Issue 131. The original proposal had
deficiencies as outlined by the chairs. Paul is aware of this as I reminded
him in January.

My suggestion would be to do the following:

1. Keep Ian's drawfocusring methods. They are acceptable to the
accessibility task force and they separate out drawFocusRing into two
functions drawSystemFocusRing and drawCustomFocusRing eliminating the need
for canDrawCustom per below.
2. Include back Chapter 11 on Caret and Selection Management. This section
was approved by the chairs prior to the decision to vacate.
3. Review the new text baseline proposal to see if it sufficiently meets
your needs. The text baseline in textmetrics provides information to the
author to enable the author to compute a focus ring's or caret's bounds.

This is certainly relevant information.  Thanks for forwarding it.

The proposal submitted previously continues to not specify the baseline.
  Perhaps I missed it, but nothing in that email above specifically
supports the removal of the canDrawCustom parameter from drawFocusRing.
