[webkit-dev] Determining the device pixel density of target device

[AgentX]

I was working with *responsive images* in Webkit and I came across this
*‘deviceScaleFactor’* attribute with determines the pixel density on the
target device.
I was unable to find out how does Webkit determine it, that is which
functions does it use and where can I find them in the Source Code? All I
was able to find was that it used a function *‘page->deviceScaleFactor()’*
which somehow returned the scale factor but I was unable to find the exact
function which actually computes the scale factor.

Any help here would be highly appreciated!!
