\brief
Adds a texture to the Texture Library. But this does not mean that the

transfer all textures into the GPU.

Number of pixels in this Mesh.

Pointer to the first in a contiguous array of SHMathVec3s that define vertex
positions.

Handle to the created Texture. This is not valid to be used until a call to

Device used to create and update the buffers.
