demo project to reproduce the issue

BackImage transparency becomes black when angle <> 0 and when images is a scaled TWICImage (since v38).
The size of the displayed image is often wrong (sometimes smaller, sometimes bigger) when angle = 0 (since v39). When we change the angle the image has the rieght size.

The image size has more bugs in HDPI apps.
