Textures

Now, textures are supported! replace_kd, replace_all and blend_kd are texture modes which can be used for blending/replacing the texture with the shading color of the object. Nearest and bilinear interpolation methods are implemented.

Implementing textures was more challenging than my expectations. Specifically, getting the correct output for non-uniformly scaled spheres was a really satisfactory moment.
