Oh, the Phoenix version of wxWidgets was updated between when they added
the EGL canvas and when they added the option to disable the EGL canvas
apparently. I have opened an issue with Pheonix to see if they will bump
their bundled wx version to a more recent version (that will include the
option of disabling EGL). I am also in the process of making our code work
with EGL, but I have been sidetracked by some other items, so I haven't
gotten it wrapped up yet.
