           Summary: Merging SATURATED_LAYOUT_ARITHMETIC flag into
                    SUBPIXEL_LAYOUT
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jfernandez at igalia.com


The SATURATED_LAYOUT_ARITHMETIC flag is intended to protect against potential arithmetic overflow certain layout and rendering operations once the SUBPIXEL_LAYOUT is enabled. After some discussion in the mailing list, it seems that enabling SATURATED_LAYOUT_ARITHMETIC whenever the SUBPIXEL_LAYOUT flag is enabled is more than recommended. 

Since the SATURATED_LAYOUT_ARITHMETIC flag makes no sense without SUBPIXEL_LAYOUT, actually there is an assertion preventing this, it seems that the most sensible action is to merge the SATURATED_LAYOUT_ARITHMETIC logic into the SUBPIXEL_LAYOUT, and eventually removing it.
