The ANSI escape sequence translation layer in TUI mode strips italic
or underlined text modes silently. You cannot output text formatted
like that using `TuiWindow.write` in Python at the moment.
Parse the ANSI escape sequences for italic and underlined text into
the `ui_file_style` structure and apply it to the TUI window when
applying styles, similar to preserving the bold/dim state already.
A script like this shows italic and underlined text correctly now.
```python
import gdb
class TestTUIWindow:
_tui_window: gdb.TuiWindow
def __init__(self, tui_window: gdb.TuiWindow) -> None:
self._tui_window = tui_window
self._tui_window.title = "colors test"
def render(self) -> None:
self._tui_window.write("""
\x1b[4mThis is underlined.\x1b[24m And normal text.
\x1b[3mThis is italic.\x1b[23m And normal text.
""", True)
gdb.register_window_type("colortest", TestTUIWindow)
```
And launching it with
```
source the_above_script.py
tui new-layout test colortest 1 cmd 1
layout test
```
