Shaders (1.14 to 1.15)
 - void rendering
 - 1.14 leash has no lightmap
 - normalmatrix for mooshroom mushrooms, particles (1.14 is also strange)
 - at_tangent on entities/block entities
 - calculate normal, at_tangent and midtex only when used by the shader pack

FIXME 1.15
 - fix for 1.14 shader packs in 1.15
 a) switch TU 1 (lightmap) and 2 (normals)
 b) replace gl_TextureMatrix[1] -> gl_TextureMatrix[2] 
 c) replace gl_MultiTexCoord1 -> gl_MultiTexCoord2
