This basically works apart from the shadow, which appears in a weird form (see the scaled red button in the screenshot, the blue button is full size). What actually appears to happen is that the shadow is in 4 "corner" bitmaps that overlap to produce an odd effect. Does anyone know how this can be fixed? 回答1: This looks interesting! Unfortunately, I
