From b10fa67605bc162cb5d6b608a2d83c48f4a7e27a Mon Sep 17 00:00:00 2001 From: Allan Sandfeld Jensen Date: Thu, 29 Jan 2015 12:29:36 +0100 Subject: Remove unused qdrawhelper_sse_p.h header This header has not compiled since the MMX header it includes was removed in 2011. It appears to be completely unused.
