Implement additional indentation for line breaking when word wrap is on

[rogeriodec]

Godot version:
3.1 rc2

OS/device including version:
Windows 10 x64

Issue description:
When word wrap option in on, the line breaking put the broken part left aligned with the starting line:

This is not aesthetically good and can lead to confusion in reading the code.
It would be best to insert an additional indentation for the broken parts, thus differentiating them from the first line:

It should be possible to fix this here:

godot/scene/gui/text_edit.cpp

Line 869 in 6697fd9

int indent_px = line_wrap_index != 0 ? get_indent_level(line) * cache.font->get_char_size(' ').width : 0;

Note that the amount of additional indent should be configurable on the TextEdit instance.

is anyone working on it? coz i would like to work on it

[bojidar-bg]

@satyayelgatte Feel free to work on it, I don't know of anyone having "claimed" it. Worst case, we will get two identical PRs.

Is the issue still up for grabs?

@Chinmaygoyal It seems nobody is currently working on it, so go ahead 🙂

I must express a deep need for this to work. there is no getting around it. writing paragraphs in a literary way for npc dialogue is a nightmare. either all the indentation being gone makes your code look like this:

or you are forced to write your big paragraphs without word wrap and manually reformat for entire minutes any time you want to change a sentence in the middle of it. there is no winning in this situation.

if word wrap worked properly with indenting strings specifically, your code wouldn't look bad while your large string blocks would stay readable. Word wrap being used on strings only would be better than simply uniformly adding indents.
