ef45a646a7 [External patch] Source-over support for SkLumaXfermode. 
This is a patch by Andrei Parvu <parvu@adobe.com> (Adobe CLA signer).

Original CL/review: https://codereview.chromium.org/24078006/

GM:lumamode will need rebaselining after landing this.

---

  In order to use CSS luminance masking, we need to be able to create an
  instance of SkLumaXfermode which can receive a kSrcOver mode, and applies
  that mode after converting the source using the luminance-to-alpha
  coefficients.

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
