[PATCH v4 6/7] composite: Use DamageSetReportAfterOp

[ville.syrjala at nokia.com]

From: Ville Syrjälä <ville.syrjala at nokia.com>

Use the "report after" damage mode for marking the automatically
redirected as damaged. Avoids a premature window tree update triggered
by compSourceValidate eg. during a CopyArea request. If the window is
marked as damaged before the CopyArea has actaully happened, the window
tree update will copy stale data to the parent.
