Canvas drawTextUnchecked does't always draw when using maxWidth

Reviewed by Mike Wyrzykowski.
When a `maxWidth` is provided, and is smaller than the actual text width,
the text is shrunk by translating and scaling the context.
However the computed `textRect` is not changed accordingly, so its
intersection with the updated context clip is now incorrect, leading to
some texts not being drawn at all.
The fix here is never to optimize out `maxWidth`-shortened texts.
