Joe Gregorio a8fabd3f28 Fiddle can use EGL if available.
To test this turn on egl, e.g. --args='skia_use_egl=true', and run by altering the
library path to point to the right directory of the EGL driver you want to use, for example:

  LD_LIBRARY_PATH=/usr/lib/nvidia-367/ ./out/Release/fiddle  | ./tools/fiddle/parse-fiddle-output
