std::optional< glm::dvec2 >	operator() (const AccessorView< AccessorTypes::VEC2< float > > &value)
	Attempts to obtain a `glm::dvec2` at the given index from an accessor over a vec2 of floats. If the index is invalid, `std::nullopt` is returned instead.

template<typename T >
std::optional< glm::dvec2 >	operator() (const AccessorView< AccessorTypes::VEC2< T > > &value)
	Attempts to obtain a `glm::dvec2` at the given index from an accessor over a vec2. The values will be cast to `double` and normalized based on `std::numeric_limits<T>::max()`. If the index is invalid, `std::nullopt` is returned instead.

Public Attributes
int64_t	index
	The index of texcoords to obtain.

Detailed Description

Visitor that retrieves the texture coordinates from the given accessor type as a glm::dvec2. This should be initialized with the target index.

There are technically no invalid UV values because of clamp / wrap behavior, so we use std::nullopt to denote an erroneous value.
