Workaround errors when loading wallpapers made recently (#244)

Browse Source 
* Add sampler2DComparison and uint to known types

* Ignore unsupported `#require` preprocessor directive

`#require LightingV1` is found in generic4.frag, genericimage4.frag, ...

* Mark _alias_* textures as FBOs

Currently not supported, but prevents loading from the file, thereby
avoiding CAssetLoadException
