    // Walter et al. 2007, "Microfacet Models for Refraction through Rough Surfaces"

    // In mediump, there are two problems computing 1.0 - NoH^2
    // 1) 1.0 - NoH^2 suffers floating point cancellation when NoH^2 is close to 1 (highlights)
    // 2) NoH doesn't have enough precision around 1.0
    // Both problem can be fixed by computing 1-NoH^2 in highp and providing NoH in highp as well

    // However, we can do better using Lagrange's identity:

Connect device via USB and make sure debugging is working.
adb tcpip 5555
adb connect <DEVICE_IP_ADDRESS>:5555
Disconnect USB and proceed with wireless debugging.
adb -s <DEVICE_IP_ADDRESS>:5555 usb to switch back when done.
