<pre>Merge <a href="http://trac.webkit.org/projects/webkit/changeset/206067">r206067</a> - [GTK] Move the rendering of auth dialog shadow to the auth dialog widget
https://bugs.webkit.org/show_bug.cgi?id=162061

Reviewed by Michael Catanzaro.

Instead of rendering the shadow in the web view, we can let the auth dialog do it. This fixes the rendering of
the shadow in Wayland when using gdk_cairo_draw_from_gl().

* UIProcess/API/gtk/WebKitAuthenticationDialog.cpp:
(webkitAuthenticationDialogDraw): Draw the shadow before rendering the child.
(webkitAuthenticationDialogSizeAllocate): Center the child on the allocated space.
(webkit_authentication_dialog_class_init): Add size_allocate implementation.
* UIProcess/API/gtk/WebKitWebViewBase.cpp:
(webkitWebViewBaseDraw): Do not draw the shadow when auth dialog is present.
(webkitWebViewBaseSizeAllocate): Give the whole web view allocation to the auth dialog.</pre>
