/*
@remarks
A table has a number of lines. These lines seem to correspond with rows, except in the case of
rows spanning more than one line. Each line contains a number of boxes/cells.

AutoFormat properties are retrieved and stored in a grid of 16 table boxes. A sampling approach
is used to read the data. 4 lines are picked, and 4 boxes are picked from each.

The line picking and box picking algorithms are similar. We start at the first line/box, and pick
lines/boxes one by one for a maximum of 3. The 4th line/box is the last line/box in the current
table/line. If we hit the end of lines/boxes, the last line/box encountered is picked several times.

For example, in a 2x3 table, the 4 lines will be [0, 1, 1, 1]. In each line, the boxes will be
[0, 1, 2, 2]. In a 6x5 table, the 4 lines will be [0, 1, 2, 4] and the boxes per line will be
[0, 1, 2, 5].

As you can see, property extraction/application is lossless for tables that are 4x4 or smaller
(and in fact has a bit of redundancy). For larger tables, we lose any individual cell formatting
for the range [(3,rows - 1) -> (3, cols - 1)]. That formatting is replaced by formatting from
the saved cells:

            0            1            2           3           4           5

        +-----------+-----------+-----------+-----------+-----------+-----------+

The properties saved are divided into three categories:
    1. Character properties: Font, font size, weight, etc.
    2. Box properties: Box, cell background
    3. Table properties: Properties that are set in the Table->Table Properties dialog.

Character and box properties are stored per cell (and are lossy for tables larger than 4x4). Table
properties are stored per-table, and are lossless.
