           Summary: HighDPI - can't use style.width to scale
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGL
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mdavids at gmail.com


In other browsers, to create a high DPI WebGL context, you can create a canvas at 2x size and scale it with CSS width/height.

In Safari, this does not work. The image does not look crisp. Instead, you need to use webkit-transform: scale to do the scaling.

You can see this by going to http://google.com/maps?force=webgl and spoofing Chrome. When you spoof the UA, text labels are blurry. When you don't, they're sharp.
