GLSL, Array of textures of differing size

Question

When doing multitexturing in GLSL, is there anyway to have an indexable array of samplers where each texture is a different size? This syntax isn\'t valid:

u

Not yet. Maybe this gets added to a later OpenGL version down the road, but I doubt it.

But then I can't iterate through them, which is a real pain in the ass. Is there a solution?

As a workaround you could use Array Textures and use only subregions of each layer. Use a vec4 array to store the boudaries of each picture on each layer.
