enhance(MFM): add parameters to rotate

[Johann150]

What

The x and y parameters are added to the $[rotate ] MFM function rendering, analogous to the $[spin ] function.

Why

fix #8523

[ThatOneCalculator]

Doing $[rotate.x or $[rotate.y just causes the thing being rotated to dissapear

Regular:

X:

Y:

[Johann150]

Yes thats because the default angle is 90°. Since the letters do not have any depth and you are looking at them from the side, that is not suprising. Try changing the angle.

I can't seem to figure out the syntax, as $[rotate.x=70 doesn't work

[Johann150]

The angle must be changed as before by the deg parameter, e.g. $[rotate.x,deg=45 a].

My conclusion on this:

Does it look great? Not really.
Is it bad? No.
Could it possibly be used in some cool #mfmart? Maybe.
Should it be added? Yea, more MFM options imo is never really a bad thing

Note on compatibility with forking: In Groundpolis, rotateX and rotateY are preceded by perspective(128px). (But probably syuilo does not care about compatibility with forking.)

PS: This comes from $[spin]

[Johann150]

I think it would be a good idea to add here too:

without perspective it can cause strange empty space

with perspective(128px) it looks better in my opinion

Very tiny bug(?): the start of text gets cut off in chat bubbles
