           Summary: CSS Masks use PNG Alpha, which is sub-optimal
           Product: WebKit
           Version: 525.x (Safari 3.1)
          Platform: PC
        OS/Version: Windows Vista
            Status: UNCONFIRMED
          Severity: Enhancement
          Priority: P5
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mail at matthewwilcox.com


Reporting here as that's what the page at http://webkit.org/blog/181/css-masks/
asks us to do.

CSS Masks appear to use Alpha channels to operate, which means we must use
PNGs? PNGs with full alpha channels are 24bit, which makes the file size huge.
Why can't Webkit map grey-scale to opacity so we can use JPGs or GIFs instead?
white = transparent, black = opaque. This is what most 3D applications use to
describe transparency.
