Using text-transform CSS property is not applied to canvas text, therefore text might be truncated incorrectly.

Example using text-transform: uppercase:

Hi @MuffinFox , thanks for reporting the issue. Will take the time to apply text-transform to canvas text. Feel free to submit the PR if you want.
