Subject: [PATCH]glamor: Fix dashed line rendering.
Patch-mainline: fe0b297420fc1de8a7fab28457d0864b3182e967
References: boo#1021803
Signed-off-by: Max Staudt <mstaudt@suse.de>

We were binding the screen pixmap as the dash and sampling its alpha,
which is usually just 1.0 (no dashing at all).

Please cherry-pick this to active stable branches.
