creates a predefined image model given a label

(create-model :ushort-555-rgb) => {:type :color :label :ushort-555-rgb :channel {:count 1 :fn vector :inv first} :meta {:type Short/TYPE :span 1} :data {:red {:type Byte/TYPE :channel 0 :index 0 :access 10 5} :green {:type Byte/TYPE :channel 0 :index 0 :access 5 5} :blue {:type Byte/TYPE :channel 0 :index 0 :access 0 5}}}

creates a model with overwrites

(model) => :3-byte-bgr :3-byte-rgb :3ch-byte-rgb :4-byte-abgr :4-byte-argb :4ch-byte-argb :byte-binary :byte-gray :int-argb :int-bgr :int-rgb :standard-argb :standard-gray :ushort-555-rgb :ushort-565-rgb :ushort-gray

(model :int-rgb {:type :stuff :data :none :channel {:hello :world}}) => (contains-in {:type :stuff, :data :none, :channel {:count 1, :hello :world}})

creates a inverse access table for setting data within an image

;; channel 0, 0th index = (i1>>3)«11 + (i2»2)«6 + i3»3 (model-inv-table (model :ushort-565-rgb)) => {0 {0 {1 11 5, 2 5 6, 3 0 5}}}
