commit-bot@chromium.org eaa7797990 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

DEPS Adds poppler and dependencies to DEPS. This is a pre-CL for 20220002, and getting DEPS committed first is necessary to get the trybots to run on the larger CL (since the trybots do 'gclient sync' before patching). 2013-08-02 19:10:06 +00:00
