Ell 1f76013d1e app: add "clip" parameter to gimp_display_shell_untransform_viewport()
... which specifies whether to clip the viewport to the canvas
(previously, it would always be clipped).  Use the appropriate
value in all callers, depending on the shell's "show all" mode.  In
particular, this commit avoids clipping the image projection's
priority rect to the canvas in "show all" mode.
