The GLSL ES 1.0 spec made these features optional. With
OES_standard_derivatives they are guaranteed to be available
but currently the extension must be enabled to use them.
Instead this changes the code to check if the driver supports
the extension and if so always enables them.
This fixes compiler errors in Google Earth VR.
