[whatwg] Clipping text in in canvas

[David Dailey]

Last I checked applying a clipPath to text in SVG works consistently across
browsers, and there it remains accessible: to screen readers, indexing,
searching, drag-to-select, etc. Why would one want a bunch of pixels that
resemble text?

Just saying,
David

Subject: [whatwg] Clipping text in in canvas

The canvas specification maintains:

    These shapes are painted without affecting the current path, and are
subject to shadow effects, global alpha, the clipping region, and global
composition operators. [0]

But no browsers I tested actually implement the "clipping region" part.
Should this be removed for backwards compatibility reasons? Should we
introduce a new method of clipping text be introduced, or should we just
require users who want to draw clipped text to draw to a scratch canvas and
use drawImage to copy the pixels?
