Zhigang Gong da66a76f27 Revert "glamor: Don't need to read dest if op is SRC or CLEAR."
This reverts commit eb16fe0b7c8ea27b5cf9122d02e48bf585495228.
As currently glamor_prepare_access/finish_access will touch
the whole pixmap, not just the request region, then write only
mode will not work correctly. We may need to revisit all fallback
case, and convert the image to the right size before do the
prepare/finish processing.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
following article:
