Feature request: OpenType Font Variation support

[Krasnaya Ploshchad’]

OpenType 1.8 introduced font variation, this technology allowing a font integrating multiple font weights, metrics and styles into single font file ("variable fonts"), and doing such transforms if a font having such data.

To implement this feature, we can accept CSS font-variation-settings (https://developer.mozilla.org/en-US/docs/Web/CSS/font-variation-settings) and other related properties inserted into text areas, and when a specific font variation instance is used, we need to transform it into static glyphs if a text object is transformed as paths. We need also implement an interface to adjust the font variation. Pango got this support in version 1.41.0, so we are reasonable to do it.
Adobe Illustrator CC 2018 is already implemented.

As a matter of fact Tavmjong is already working on support for font variations, see [1] for some details.

The current development version [2] already has some support if you want to get involved into testing.

GUI support has been added to trunk. A series of sliders to set axes will appear in the Text and Font dialog when a font with variations is selected.

Variable font support is mostly there for Inkscape 1.0, so marking this as 'fix committed'.
