A text layout should be able to have indents for consecutive sentences or for the first sentence #12255

Steps to Reproduce

I am trying to layout a poem: when the text line is too long for the widget width, the line should be softwrapped to the next line, with an indent: everybody understands that the sentence should have been on one line.

Also, it is quite familiar to indent the first line of a paragraph. So it should be possible to somehow do s softwrap indent or a first line indent (this could also be negative, so the first line of a sentence protrudes to the left in the case of left-to-right example.

At the moment I resolved it by creating a function that calculates the width of words in a sentence, and when the sentence is too long for the width of the widget, insert a newline and some spaces.

The calculation however, is crude: it does not take into account ligatures and different widths of characters.

If the problem is with your application's rendering, please attach a screenshot and any relevant source code.
