Mac: fix invalid context in imageForGlyph
The bounding rectangle may have negative width or height when a
graphics view with text is rotated in certain angles. Make
sure that the image width and height are positive, otherwise the
context will be null and the following messages can be seen in
test logs:
<Error>: CGContextSetFontSize: invalid context 0x0
