Phrase element - letter spacing issue

[KaliedaRik]

When adding letter spacing to a multiline Phrase entity, the spacing applies itself in front of the first letter of the text, both when left-justified and full-justified.

To view the issue, go to demo Canvas 017 and apply letter spacing to the entity.

The above is an artefact of the test, not the library code, caused by the requirement to include a letter - in this case a soft hyphen (& shy ;) at the start of the text to get the initial italic formatting to stick.

Thus the focus of this issue changes from fixing Demo Canvas-017 (which is not broken) to finding out a way to start the Phrase text with a section marker which the code will act on, thus removing the need for clumsy workarounds (such as adding in a soft hyphen at the start of the text)

While we're at it, we need to add in right-to-left text support - we have it for text along a path, but not for normal text.
