Correctly pre-clip paths when recording display lists

Bug #6836448
External bug: http://code.google.com/p/android/issues/detail?id=34946

DO NOT MERGE

DisplayListRenderer::drawPath was not invoking quickReject() properly,
passing x,y,width,height instead of left,top,right,bottom. A path
could thus get rejected when it should be drawn instead.

While working on this change I found a similar issue with another
drawing command, drawBitmapData().
