11/* an intro to the data structure:
12 *
13 * vector keymap[] is grouped.
14 *
15 * inside each group, elements are sorted by the criteria given by compare_priority().
16 * the lookup of keysym is done in two steps:
17 * 1) locate the group corresponds to the keysym;
18 * 2) do a linear search inside the group.
19 *
20 * array hash[] effectively defines a map from a keysym to a group in keymap[].
21 *
22 * each group has its address(the index of first group element in keymap[]),
23 * which is computed and stored in hash[].
24 * hash[] stores the addresses in the form of:
25 * index: 0 I1 I2 I3 In
26 * value: 0...0, A1...A1, A2...A2, A3...A3, ..., An...An
27 * where
28 * A1 = 0;
29 * Ai+1 = N1 + N2 + ... + Ni.
30 * it is computed from hash_budget_size[]:
31 * index: 0 I1 I2 I3 In
32 * value: 0...0, N1, 0...0, N2, 0...0, N3, ..., Nn, 0...0
33 * 0...0, 0.......0, N1.....N1, N1+N2...N1+N2, ... (the compution of hash[])
34 * or we can say
35 * hash_budget_size[Ii] = Ni; hash_budget_size[elsewhere] = 0,
36 * where
37 * set {I1, I2, ..., In} = { hashkey of keymap[0]->keysym, ..., keymap[keymap.size-1]->keysym }
38 * where hashkey of keymap[i]->keysym = keymap[i]->keysym & KEYSYM_HASH_MASK
39 * n(the number of groups) = the number of non-zero member of hash_budget_size[];
40 * Ni(the size of group i) = hash_budget_size[Ii].
