Huge JavaFX performance drop in Debian Jessie

[Chien Yang]

Hi Chris,

JavaFX may run on Intel GMA 3150, but it is not a supported GPU. There 
is a high likelihood that the drop in performance is caused by the 
switch from sw pipe (Debian Wheezy) to es2 pipe (Debian Jessie). GMA 
3150 is an underpowered GPU for JavaFX's es2 pipe. You can try forcing 
JavaFX to use its sw pipe by specifying -Dprism.order=sw in the run command.
