Welly depends on discrete GPU

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open Welly, GPU switched to discrete
2. Close the window, GPU still on discrete
3. Quit Welly, GPU switched back to integrated

What is the expected output? What do you see instead?
Expect Welly to work under either discrete or integrated GPU, but Welly seems 
to depend on discrete GPU.

What version of the product are you using? On what operating system?
Welly 2.64 on OS X 10.8.2 on a Mid-2012 non-Retina MBP

Please provide any additional information below.
MBP can become very hot when discrete GPU keeps powered on. Used gfxCardStatus 
to confirm.

Append

    <key>NSSupportsAutomaticGraphicsSwitching</key>
    <true/>

before </dist> in Info.plist fixed the problem.
