Gate the new resizing behavior behind new option

This interferes with resizing plugins using resize handles, and since it
only helps with two buggy plugins this seems like the best solution
here.

 ### TODOs
 
-- Remove the remaining mentions of `editor_double_embed` from the readme.
+- Remove the note after the `editor_coordinate_hack` compatibility option in the
+  readme.
+
+### Added
+
+- Added a new `editor_coordinate_hack` option which replaces
+  `editor_double_embed`. This can be useful with buggy plugins that have their
+  editor GUIs misaligned after resizing the window because they draw their GUI
+  based on (top level) window's absolute screen coordinates instead of their own
+  relative coordinates. The known plugins that can benefit from this are
+  _PSPaudioware E27_ and _Soundtoys Crystallizer_.
 
 ### Removed
 
-- The `editor_double_embed` option added in yabridge 1.4.0 has been removed.
-  This option was added to work around _PSPaudioware E27_ which used its parent
-  window's position as an offset for drawing its GUI, and without this option
-  that GUI would be misaligned. The below change to yabridge's embedding method
-  supersedes this option, as it also fixes a similar issue for another plugin.
-
-### Changed
-
-- Yabridge's Wine window embedding now takes more measures to make sure that the
-  plugin draws itself properly in the top left corner of the window when windows
-  are being resized. This is needed for some buggy plugins that draw window
-  based on absolute screen coordinates, instead of their positioning within the
-  parent window, like the _Soundtoys_ plugins and older _PSPaudioware_ plugins.
-
-### Fixed
-
-- Fixed an offset editor GUI after clicking the 'Tweak' button in _Soundtoys
-  Crytallizer_.
+- The `editor_double_embed` option added in yabridge 1.4.0 has been removed as
+  the `editor_coordinate_hack` option supersedes it.
