make EDBM_index_arrays's stay in memory, blender was allocating an array and filling it for verts/edges/faces on every redraw.
this may introduce bugs which I didn't catch, but they are very easy to identify in a debug build which has asserts to ensure the arrays are valid before use.
in my own test drawing ~98,304 quads - this gave an overall ~16% drawing speedup.
