b06a3a9a6f Always set tabulation width 
Not setting it makes Pango use a slightly different value of tabulation width,
breaking a test.

97a5aaea07 Remove work done twice when splitting lines between characters 
There used to be a problem with WRAP_CHAR method of Pango, but it's fixed. As
nothing is said in Pango's Changelog, the probem may have been in our heads,
and that wouldn't be surprising at all.

a27146c9a7 Don't reset layout text when there's no soft hyphens in text 
Setting text is slow and should be avoided when possible. We should probably
avoid get_first_line too and keep the original one here.

039b0a680d Don't rely on iter_get_index to get current line break index 
pango_layout_iter_get_index gives the visual order, not the logical order, so
we can't rely on this to fix the line break index.

Fix #828.

We want to keep resume_at for example when the text ends with a forced end of
line.

4e6d449c5c Don't store Pango layout between page layout and drawing steps 
Creating Pango layouts during page layout and recreating them when drawing
pages is a little bit slower but frees A LOT of memory.

5f0723a727 Only keep two lines when creating text layouts 
Layouts are used to render only one line and know if there's a second one. We
can thus ignore the text after the two first lines.

3b52fb058e Don't optimize resume_at when splitting lines with trailing spaces 
Fix #586.

For some reason I don't really understand, stripping trailing spaces that would
make the line too long can't be optimized when the space is at the end of the
block. Returning None instead of the index of the last letter should be
possible, but it breaks the rendering when the first letter of the next line
box starts with a character that doesn't allow line breaks after spaces (many
punctuation characters for example) and that doesn't allow line wrap.

This change shouldn't be harmful, as the removed code lines were just cleaning
the resume_at value without changing the logic of line breaking. I suppose that
there's a bug somewhere else.
