[PROBLEM] Installing a kodi-visualization package

[Nachteule]

Waveform and spectrum are also already included in the xbian-package-xbmc package

I have now made a few tests, result:
fishbmc does not work on a rpi3b+, shadertoy works partially (some shaders work, some don't. why that is, I don't know, probably because of the GLES version).

fishbmc and shadertoy, however, work completely on a raspberry pi4, but a different GLES version (v3) is used, whereas on pi3 it is v2.
