 ||[https://bugs.webkit.org/show_bug.cgi?id=29279 #29279]||Decode images to RGB16 or smaller (instead of RGB32) to conserve memory. The patch introduces new API to Qt.||||||
 ||||Go through the Palm changes and consider adopting them. Currently candidates are: Use stack/class memory in CSSParser, use JDCT_Fast for Jpeg decoding (to be achieved with QImageReader to set quality to 49), changes to Cached* to throw away encoded data more early. Palm avoids floating point operation on premultiplied alpha in setRGBA.||||||
-||[https://bugs.webkit.org/show_bug.cgi?id=30740 #30740]||Using QImageReader::setQuality(49) will use JDCT_IFAST and promises to give a 5% speedup on image_cycling.||||||
-||[https://bugs.webkit.org/show_bug.cgi?id=30210 #30210]||Create Embedded profile that will tune for embedded usage. This can mean to save memory in favor of speed, add a speed gain by avoiding certain operations, trading image quality for speed||||||
-||[https://bugs.webkit.org/show_bug.cgi?id=29443 #29443]||Using WebCore's FontCache decreases memory usage. Change done by Benjamin Poulain||||||

 ||||~~Change CursorQt.cpp to not create QPixmap's right away but only on first load. This will be a minor memory improvement.~~ Using DEFINE_LOCAL_STATIC had a negative impact on memory usage.||||||
