getsize_multiline doesn't take into account characters that extend below the baseline
### What did you do?

I'm using `getsize_multiline` to compute the size of a text label that I render to an image. The image is exactly the size of the text label.

I noticed that my text labels where cropped; specifically, when there are letters like `p` or `g` (which extend below the baseline) on the last line of text, these letters get cropped.

The problem doesn't affect `getsize`, and can easily be exhibited by comparing the sizes reported by `getsize` vs `getsize_multiline` for a single line string like `g`.

Example:

```python
from PIL import ImageFont
font = ImageFont.truetype("DroidSans", 20)
print(font.getsize("g"))
print(font.getsize_multiline("g"))
```

### What did you expect to happen?

The `getsize` and `getsize_multiline` methods should return the same size.

### What actually happened?

With `DroidSans` in size 20:
- `getsize` returns (10,24)
- `getsize_multiline` returns (10,19)

The `g` actually extends below if I create a label of size 10,19 and draw the string `g` on it, the `g` gets cropped.

### What are your OS, Python and Pillow versions?

* OS: Arch Linux
* Python: 3.9
* Pillow: 8.4.0

```python
#!/usr/bin/env python

from PIL import Image, ImageFont, ImageDraw

font = ImageFont.truetype("DroidSans", 20)

text = "gÂp"

size = font.getsize(text)
image = Image.new("RGB", size)
draw = ImageDraw.Draw(image)
draw.text((0, 0), text, font=font)
image.save("getsize.png")

size = font.getsize_multiline(text)
image = Image.new("RGB", size)
draw = ImageDraw.Draw(image)
draw.text((0, 0), text, font=font)
image.save("getsize_multiline.png")
```

I imagine that the logic in getsize_multiline doesn't take into accounts characters that extend below the baseline. For now I'm going to just add a bit of padding on the last line 😅 but I guess there has to be a better way.


Of course, _immediately_ after opening that issue, I find a very promising method: `getmetrics()`, that precisely returns the ascent and the descend of a font. It looks like all I need to do is add the "descent" at the bottom of the label. I'll check that and if it works, I'll see if I can propose a patch for `getsize_multiline` and associated tests.
Both `getsize` or `getsize_multilne` are often inaccurate (especially with italics or accents), but unfortunately they might never get fixed due to backwards compatibility (also, the definition of size can change depending on your use case, so the expected return value is unclear). I would not recommend using them in new code. The [docs for `getsize`](https://pillow.readthedocs.io/en/stable/_modules/PIL/ImageFont.html#FreeTypeFont.getsize_multiline) have this warning:

> For historical reasons this function measures text height from the ascender line instead of the top, see Text anchors. If you wish to measure text height from the top, it is recommended to use the bottom value of getbbox() with anchor='lt' instead.

It seems I didn't add a warning to the multiline version, likely because I didn't add a `getbbox_multiline` function (it would be an exact copy-paste). However, in most cases you will be using a font to draw onto an image using `ImageDraw.text`, which provides the two equivalent functions `textsize` and `multiline_textsize`. The [docs for `multiline_textsize`](https://pillow.readthedocs.io/en/stable/reference/ImageDraw.html#PIL.ImageDraw.ImageDraw.multiline_textsize) do have a similar warning:

> For historical reasons this function measures text height as the distance between the top ascender line and bottom descender line, not the top and bottom of the text, see Text anchors. If you wish to measure text height from the top to the bottom of text, it is recommended to use multiline_textbbox() instead.

In fact, I think this might not be entirely accurate due to the way Pillow computes line spacing - glancing at the source I suspect it is measuring to the bottom baseline instead in most cases and ignoring the last descender line like you mentioned.

Instead, I believe [`ImageDraw.multiline_textbbox`](https://pillow.readthedocs.io/en/stable/reference/ImageDraw.html#PIL.ImageDraw.ImageDraw.multiline_textbbox) is the function you are looking for. It's documentation also provides a brief explanation:

> The bounding box includes extra margins for some fonts, e.g. italics or accents.

As for why `getsize` and `getsize_multiline` are not deprecated, IIRC I didn't propose this because the new functions work only with TrueType fonts, while the old functions work correctly with old "PIL" fonts. However, it might make sense to deprecate the old functions for TrueType fonts only.

Edit: For more information see #4959 and the linked issues.

This deprecation sounds reasonable.

What do others think? 

If adding warnings now (Pillow 9.0.0, 2022-01-02), it would be eligible for removal in Pillow 10.0.0 (2023-07-01), giving a nice long deprecation period.

Yes indeed, thank you so much! I have one follow-up question: `ImageDraw.multiline_textbbox` requires an `ImageDraw` instance, but my program creates the image _after_ computing the text size (since the image holds the text label and nothing else). I did a little experiment and it looks like I can create an image of size (0,0) and use that to call `multiline_textbbox`, then create my final image with the proper size. Is that the right thing to do? Or might that break in the future?

Thank you so much!
I don't think that what you're describing should break in the future - and yes, it sounds like a reasonable way of doing things.

If we deprecate those, we should also then add `getbbox_multliline` and `TransposedFont.getbbox`, yes?
> If we deprecate those, we should also then add getbbox_multliline and TransposedFont.getbbox, yes?

Probably. That is what I was unsure about and why I didn't propose deprecating earlier.

I'll take a look at this as part of https://github.com/python-pillow/Pillow/pull/6195#discussion_r847410876.
