     This involves either extending the pixman library to support the new format, or write code for
     Porter-Duff compositing on the new format and make cairo use them for ARGB64.    
+    Conversions between the 16-bit floats used by colour spaces such as scRGB and 32-bit floats
+    should use the algorithms explained in Jeroen van der Zijp’s [Fast Half Float Conversions](ftp://www.fox-toolkit.org/pub/fasthalffloatconversion.pdf).
   * [Easy] Add a performance/conformance suite for the vector backends.
