From fd2e4803a07e60f447c5734a39fac561b1fc4407 Mon Sep 17 00:00:00 2001 From: "Lubomir I. Ivanov" Date: Sun, 29 Oct 2017 17:58:19 +0200 Subject: README: add notes about the OpenGL requirements This commit creates a "System Requirements" section in the README. Thus far this wasn't required but the Google maps plugin introduced a complication. The next patch will attempt to add the automatic "fall back to a software renderer". Signed-off-by: Lubomir I.
