Titanium.UI.iPhone.MODAL_TRANSITION_STYLE_PARTIAL_CURL

When the window is presented, one corner of the current view curls up to reveal the modal view underneath. On dismissal, the curled up page unfurls itself back on top of the modal view. A modal view presented using this transition is itself prevented from presenting any additional modal views. This transition style is supported only if the window is presenting a Titanium.UI.iPhone.MODAL_PRESENTATION_FULLSCREEN modal presentation style.
