Using the current Ti SDK GA 7.1.0 Windows applications do not recognize widths nor heights set as pixels. Also the fonts seem to be hardcoded to DIP since they don't change when specifying "18px" as a value. See attached app folder of an alloy application that has 4 boxes, each with a different unit (px, dip, dp and pt)
Our application requires us to have a 1920x1400 canvas to display all the elements needed. However if the user has a screen with 2736x1824 @ 200%, the actual dip that we can use are 1368x912
The device is a surface 4 pro.
