+Subject: [PATCH 009/131] Do not apply subpixel gamma-correction on XCB
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+To match rendering of subpixel antialiased text in Qt 4.8 and other
+toolkits on X11, we should not apply gamma-correction. This also
+makes the rendering of subpixel antialiased text closer to normal
+antialiased text.
