Merge lp:~hikiko/unity/unity.bug-1087534 into lp:unity

[Eleni Maria Stea]

Bug #1087534 occurs only in a family of low capable integrated Intel GPUs. These GPUs cannot support many visual effects anyway, therefore when one of them is detected we switch to low graphics mode (and there's no blur etc).

Important note!!
This branch has only been tested on an Asus EEE 901 and a Dell Inspiron!
