New Editor's Draft of MediaStream Image Capture

Hi All,

Have uploaded a new version to Github (http://gmandyam.github.io/image-capture/), and am enclosing a PDF version in this email for archival purposes.  Please note the following changes:

a) 'zoom' setting and 'autofocus' setting added to PhotoOptions - see http://gmandyam.github.io/image-capture/#photooptions.  Note that other native focus modes are not currently considered in the specification, but I am open to suggestions.
b) Error in example corrected as per guidance in https://www.w3.org/Bugs/Public/show_bug.cgi?id=25226.

c) Provided an option for promise-based implementation of API - see http://gmandyam.github.io/image-capture/#promise-extensions-to-imagecapture.  Note that the method for changing camera settings is not a promise, as it is assumed that settings may change at any time (e.g. end user manually changing settings on the physical capture device) .  I am open to suggestions, however.

Comments/questions/corrections are all welcome.
