[kern] XXX Negate CrossKerning sign
...
Not sure why, but seems to better match GeezaPro Arabic w CoreText.
Quite possibly I'm doing something very wrong...

[kern/kerx] Fix Format2 offsetting
...
"The values in the right class table are stored pre-multiplied by the
number of bytes in a single kerning value, and the values in the left
class table are stored pre-multiplied by the number of bytes in one
row. This eliminates needing to multiply the row and column values
together to determine the location of the kerning value. The array can
be indexed by doing the right- and left-hand class mappings, adding the
class values to the address of the array, and fetching the kerning
value to which the new address points."

KernSubTableFormat2::rightClassTable and the 'right' argument to
KernSubTableFormat2::get_kerning to go unused.
