[BUG] Inconsistency With Measurement Units In API

[EldarAgalarov]

Why Plots.jl using different measurement units for font sizes, chart size, margin sizes, etc?
Why I should explicitly add "px" or "mm" suffix on margin sizing but none of them for font or chart sizing?

Make ALL those elements to use ONE measurement unit that should be pickable as base unit. For example:

plot(...,
measurementUnit = :px,
margin = 10,
titleFontSize = 8,
size = (200, 100)
)

OR add support for setting measurement units inline:

plot(...,
margin = 10px,
titleFontSize = 8px,
size = (200px, 100px)
)

plot(...,
margin = 10mm,
titleFontSize = 8mm,
size = (200mm, 100mm)
)

Plots.jl version: 1.33.0
Backend: GR
Julia version: 1.8.1

Thats unfortunately not that easy at all and so far nobody took the effort to do this. And the default unit is generally what the backend uses. So fontsizes are in pt and most other measures are in px.

No scaling of font size is really annoying, and forces to use infamous hacks as in https://docs.juliaplots.org/stable/gallery/gr/generated/gr-ref55/#gr_demo_55.
