From c143df1abdd54cf5f6aba55b916560f012846b28 Mon Sep 17 00:00:00 2001 From: Pekka Paalanen Date: Tue, 10 Mar 2015 12:52:14 +0200 Subject: [PATCH] rpi-renderer: minimal fix to zoom coordinates The patch "zoom: Use pixels instead of GL coordinates" changed the meaning of weston_output_zoom::trans_x,trans_y from GL coordinate system to global coordinates. This patch is a minimal untested change to the rpi-renderer to try and follow up on that change.
