4/// simple vertex shader. uniform requires `model: Mat4`,
5/// `perspective: Mat4` (use `Mat4::view_matrix_3d()` for 3d or `Mat4::view_matrix_2d()` for
6/// 2d/orthographic) and `camera: Mat4` (inverse camera matrix. use `Mat4::from_inverse_transform()`
7/// or call `.inverse()` before feeding the matrix into to the shader)
8///
9/// If you are new to shaders or how things render I highly recomend you check out the glium tutorial
10/// book (https://github.com/glium/glium/tree/master/book) it is where this shader is from after
11/// all
12///
13/// WARNING! if ALL vertex bindings aren't bound in the draw call your program will PANIC on most
14/// computers, HOWEVER, some don't panic, which may lead you to FALSELY believe you program will run
15/// else where
