Subject: [PATCH] GEQ flat mode for 2D
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

you still have to use a trick -> the "expand 1D" drop-down is hidden once you select a 2D-capable effect

* Create your segment with 2 colums or 2 rows (might also need "transpose"
* Select a 1D effect like chunchun
* set expand to "Pixels" or "Bar"
* now select the GEQ effect

--> Flat GEQ runs in the previously set expand mode.
