Detailed Description

GPU-friendly vertex data for instancing.

This structure matches the shader input layout and packs the instance data into a single 4x4 matrix for efficient copying. The LOD parameter is packed into the matrix[3][3] position (which is normally 1.0 for homogeneous coordinates). The matrix will be interpreted as 4 vec4 attributes (i_data0 through i_data3) by the shader.
