Add luminance mask transfer modes. This adds kSrcInLum_Mode and kDstInLum_Mode, to support CSS and SVG luminance masks (http://www.w3.org/TR/css-masking/#MaskValues , http://www.w3.org/TR/SVG/masking.html#Masking ). The transfer coefficient is computed according to http://www.w3.org/TR/2011/REC-SVG11-20110816/filters.html#feColorMatrixElement "luminance-to-alpha": luma = 0.2125 * r + 0.7154 * g + 0.0721 * b R=bsalomon@google.com, reed@google.com, robertphillips@google.com, vandebo@chromium.org Author: fmalita@chromium.org Review URL: https://chromiumcodereview.appspot.com/22918012 git-svn-id: http://skia.googlecode.com/svn/trunk@10887 2bbb7eff-a529-9590-31e7-b0007b416f81
