* is_swizzled - determines whether input bytes are in morton order
* subresources_layout - descriptor of the mipmap levels in memory
* decoded_remap - two vectors, first one contains index to read, e.g if v[0] = 1 then component 0[A] in the texture should read as component 1[R]
* - layout of vector is in A-R-G-B
* - second vector contains overrides to force the value to either 0 or 1 instead of reading from texture
* static_state - set up the texture without consideration for sampler state (useful for vertex textures which have no real sampler state on RSX)
