If you are applying your single image_map *many* times to your model (for
example, like many randomly-placed 'decals'), another way to save memory is to
first #declare the image_map in a pigment statement:

#declare my_hull_pigment = pigment{image_map{.....}}

......then use that in your scene, as the pigment in your (many) textures,
instead of a new image_map statement every time. This way, the original image
takes up memory only once. The idea is similar in concept to using a single mesh
object many times in a scene: one mesh which is 're-used', requiring no
additional memory.
