Unsupported `mask-type` style attribute in SVG

[Antoine Colombier]

Is your issue REALLY a bug?

• My issue is indeed a bug!
• I am not crazy! I will not fill out this form just to ask a question or request a feature. Pinky promise.

Is there an existing issue for this?

• I have searched the existing issues.

Is this issue related to iced?

• My hardware is compatible and my graphics drivers are up-to-date.

What happened?

Until 0.13, iced doesn't seems to support mask-type: alpha SVG style attribute.

svg example on 0.12.3 (latest crate release) with an SVG using mask-type: alpha

svg example on 0.13-dev (master) with an SVG using mask-type: alpha

Note that they are rendering issues currently, as it can be seen on the grey border. Should I open a new issue for that

The SVG used for testing
