From 5c70644070803b665f64c2d3212b55a4a3270765 Mon Sep 17 00:00:00 2001
From: Daniel Stone <daniel@fooishbar.org>

Subject: [PATCH 4/4] EGL: Specify vec2d precision qualifier in fragment shader
GLSL does not specify a default precision qualifier here, so we have to
explicitly define it. Use highp, as it gets redefined to mediump by
QGLShaderProgram when not available.
