Scale the icons when viewBox and width/height differs

[nfroidure]

The process should be:

• set the viewbox size with the viewBox attribute if it exists then, read x y width and height attributes to scale the icon to the desired width/height being preserveAspectRatio aware
• otherwise, use x y width and height attributes
• finally if none of this attributes are present, maybe deduct from the drawed elements the icon bounds ?

Hey @nfroidure this actually didn't solve the issue..
Some other guy also faced this issue with latest version.

Fantasticon has faced similar issues regarding fonts not being vertically centered properly in some cases.
