fix(line): line truncation respects alignment

[TadoTheMiner]

When rendering a Line, the line will be truncated:

• on the right for left aligned lines
• on the left for right aligned lines
• on bot sides for centered lines

E.g. "Hello World" will be rendered as "Hello", "World", "lo wo" for
left, right, centered lines respectively.

Fixes: #932
