* node-macro: modernize `node` macro * node-macro: add `CrateIdent` struct containing resolved crate paths * shaders: add trait `BufferStruct` and derive macro * shaders: `gamma_correction` and `channel_mixer` gpu nodes * shaders: `selective_color` gpu node * shaders: `brightness_contrast_classic` gpu node * shaders: append GPU to display name * node-macro: fixup doc links * shaders: consistently append " GPU" to all shader node names
