Ffimageloading: Xamarin.Mac & Xamarin.Forms.Mac support

[YZahringer]

Currently support for macOS by Xamarin is in beta with version 2.3.5. Would it be possible to provide a pre-release with macOS support?

Thanks to @Sevenish and #723 we have now a basic Mac support.

TODO:

• Xamarin.Forms support
• SVG support
• Transformations support
• WebP, GIF support
• FadeIn support

2.2.12.497 nuget with Mac support released. (Xamarin.Forms not supported yet)

[daniel-luberda]

• I added Xamarin.Forms.Mac project + sample project
• It's not working yet, as somehow renderer is not used. (Does Xamarin.Forms.Mac support custom renderers now?)

I didn't have time to take a look at this, any help with this appreciated.

[daniel-luberda]

XF fixed & Transformations added. All basic things should be implemented now :)

Missing:

• SVG support
• WebP, GIF support
• FadeIn support

Thank you, awesome work! I'm doing a Xamarin Forms application on macOS, I'll try this 😃

[daniel-luberda]

Thanks! :) Also that might be quite important fix for you: https://github.com/luberda-molinet/FFImageLoading/commit/344480d146c099b76cee4812c1d05c63a662c96a

Now, the behaviour is the same as Xamarin.Forms.Image

[daniel-luberda]

Done. Everything is working (including SVG & WebP), only GIF left.

Gif should be working as it's also implemented. But it doesn't animate. Any Mac experts here?

Code:

https://github.com/luberda-molinet/FFImageLoading/blob/master/source/FFImageLoading.Mac/Targets/NSImageViewTarget.cs#L26-L31

Any clues why it's not animating?
