windowSize not working as described

[jmhomedes]

At least in my case, working with Windows 8 x64, I've seen that with default configuration gemini is taking screenshots at 400x300 resolution. If I try to configure it on my way as described in documentation:
`
geminiOptions: {
browsers: {
"chrome-latest": {
desiredCapabilities: {
browserName: 'chrome',
version: '37.0'
}
}
},
windowSize: '1200x720'

}
`
it keeps taking screenshots at same 400x300 resolution.

Looking at the code in visualtest project's index.js I found windowSize default configured with 1024x768, so at the time of geminiOptions objects merge is the same as providing it via task runner. Same object structure. Both not working.

Then I had a look on gemini's project code and found that seems like gemini Config constructor receives correctly windowSize property inside the object param. Then it calls
var parsed = parseOptions({ options: **configData**, env: process.env, argv: process.argv });
and windowSize property keeps at root level (parsed.windowSize). The problem with it is then, constructor does
this.system = parsed.system; this._browsers = parsed.browsers;
so parsed object's root properties seems to get lost after that.

Conclusion:

finally I got it working providing windowSize at browser level (and maybe you should consider to change it in geminiOptions object if it's a generalized issue):
geminiOptions: { browsers: { "chrome-latest": { desiredCapabilities: { browserName: 'chrome', version: '37.0' }, windowSize: '1200x720' } } }
Important: is at "chrome-latest" object root level, not inside desiredCapabilities
