A few PS4 presets about complicated shader code will not work on both Intel/AMD cards.

I have made support for AMD/ATI cards with Pixel Shader 4 two months ago and some of the presets will not work properly, for example: martin - Gin Tonic on Ice, martin - enlighten me and so on.

Here are my code snippets I've tried to modify to get work with Pixel Shader 4 presets on AMD/ATI card:

- https://github.com/OfficialIncubo/BeatDrop-Music-Visualizer/blob/master/vis_milk2/plugin.cpp#L2044-L2117
- https://github.com/OfficialIncubo/BeatDrop-Music-Visualizer/blob/master/vis_milk2/plugin.cpp#L3632-L3655

You can also take a look at LoadShaderFromMemory() function if you want: https://github.com/OfficialIncubo/BeatDrop-Music-Visualizer/blob/master/vis_milk2/plugin.cpp#L3790-L4056

I have changed this feature to BETA and if anyone wants to help me getting fully working, please open a PR or tell some replies here ;)

MilkDrop3 does the same, now with error X3506: unrecognized compiler target 'ps_4_0' instead of detailed errors.
It's likely because of compiler internals, but I think we can get a fix or not.
I can't decide if I close an issue, but please tell me.
