    Description

      The default flickable velocity and deceleration is statically defined and doesn't scale with pixel density, as seen https://qt.gitorious.org/qt/qtdeclarative/source/e895bc315f9959a5dad80a8f0bf7b73bced0bde1:src/quick/items/qquickflickable.cpp#L78

      These values don't work right anymore for devices with high pixel density, for example smartphones or tablets (2500 pixels per second is too low on 300/400 ppi screens), and are not customisable apart from rebuilding Qt.
