            Bug ID: 85561
           Summary: cairo_image_surface_create() width/height limit
           Product: cairo
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: image backend
          Assignee: chris at chris-wilson.co.uk

With and height in `cairo_image_surface_create()` seems to have defined limit
on 2^15 (32768) which is more then one billion cells. But unfortunately this
limit doesn't allow to create a surface with `height = 1` and `width > 2^15`.

Why the limit is defined for width and height separately and not for a number
of cells? And how to solve the example noted above?

Thanks in advance, Martin
