Hi James, thought the following proposals may be of interest to you in light of your comments on the Firefox canvas bug [https://bugzilla.mozilla.org/show_bug.cgi?id=495912#c93]
* Modify existing Canvas 2D API to expose text baseline and facilitate drawing of focus rings [http://www.w3.org/html/wg/wiki/ChangeProposals/FocusRingTextBaseline] * Canvas hit testing [http://www.w3.org/wiki/Canvas_hit_testing] * Modify existing Canvas 2D API to include APIs that allow a screen magnifier to track caret and selection change movements[http://www.w3.org/html/wg/wiki/ChangeProposals/CaretSelectionRevised] -- with regards Steve Faulkner
