\brief
Adds a mesh to the Mesh Library. But this does not mean that the meshes have
been added yet. A call to "BuildBuffers()" is required to transfer all
meshes into the GPU.
\param vertexCount
Number of vertices in this Mesh.
\param positions
Pointer to the first in a contiguous array of SHMathVec3s that define vertex
positions.
\param texCoords
Pointer to the first in a contiguous array of SHMathVec2s that define vertex
texture coordinates.
\param tangents
Pointer to the first in a contiguous array of SHMathVec3s that define vertex
tangents.
\param normals
Pointer to the first in a contiguous array of SHMathVec3s that define vertex
normals.
\param indexCount
Number of indices in this mesh.
\param indices
Pointer to the first in a contiguous array of uint32_ts that define mesh
indices.
\return
Handle to the created Mesh. This is not valid to be used until a call to
BuildBuffers().
