           Summary: Use Skia integer primitives for drawing Chromium Linux
                    scrollbars
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: agl at chromium.org


The Skia drawLine function takes subpixel values and attempts to draw
a line with subpixel precision. This is complex and slow for drawing
scrollbars which use only vertical and horizontal lines.

This changes the Chromium Linux scrollbar code to use drawIRect.

Layout test changes will be in the Chromium tree.
