It affects the sizes of many arrays, including the FLAGS array, which
is part of every line, pad, pin, via, polygon, etc (two per byte, 64
layers = 32 bytes per object).  Also, the layergroup array is N^2 and
the global pcb->data has an array of layers (not as big a deal on
those, just mentioning them).

not sure how the gtk GUI deals with the variable number of layers in a
project, but if it still has some left-over code that uses MAX_LAYER
instead of max_layer, you'd end up with 64 somethings on the screen.
