B4A Class [custom view] GifViewer

Better implementation: https://www.b4x.com/android/forum/threads/b4x-b4xgifview-cross-platform-animated-gif-view.118550/

Simple view that shows an animated gif. Based on agraham's GifDecoder library.

The animated gifs included in this example are from giphy.com. I'm not sure whether they can be used commercially or not.

Tip: B4J ImageView supports animated gifs.

V1.20 - Images are cached once loaded. You need to add the following variable to the Main module:
B4X:
Sub Process_Globals
   Public GifsCache As Map
End Sub

Is it possible to create ,by code, a new gifviewer object from the cache???, I have already load a few gifs, then I want to create a random gifviewer-objects without loading again from the file.
