Notes

For screen readers, IE, Chrome & Firefox support the accessible canvas element sub-DOM.
Firefox & Chrome also support the drawfocus ring.

1. Does not support toDataURL()

2. Opera Mini supports the canvas element, but is unable to play animations or run other more complex applications.

Bugs

• The Android browser does not support clipping on HTML5 canvas. See the bug filed here: https://issuetracker.google.com/issues/36934492

• Older versions of iOS did not support video as a source for the canvas drawImage(), though it does appear to work as of iOS 8 test case

• Limits of toDataURL() for iOS:
  - The maximum size for decoded GIF, PNG, and TIFF images is 3 megapixels for devices with less than 256 MB RAM and 5 megapixels for devices with greater or equal than 256 MB RAM.
  - The maximum size for a canvas element is 3 megapixels for devices with less than 256 MB RAM and 5 megapixels for devices with greater or equal than 256 MB RAM.
  - JavaScript execution time is limited to 10 seconds for each top-level entry point.

• In IE 11 canvas.toDataURL() does not work if the canvas has images with data URI sources see bug

• IE 10 canvas doesn't support setLineDash or lineDashOffset see bug

• IE and Edge does not support globalAlpha for drawImage of SVG graphics. see bug see testcase
