In ME_SetParaFormat the wEffects that were being set needed to be set
rather than the dwMask.

I created a function to set the default paragraph format to ensure
consistency when this is done.  This initial paragraph format is also
now more consistent with native richedit controls.  The dwMask value
always appears to have the same value when retrieved from the native
richedit controls, so all the mask values are now initialized when the
PARAFORMAT2 structure is created.

The PARAFORMAT structure has a bit in wEffects to indicate whether the
paragraph is a table or not, so this should be used instead of a private
bTable value, since this structure can be retrieved with EM_GETPARAFORMAT.

Move those things out of the state table.

For now the atifs selection sticks to the old rules, thus it is bound to
the available and selected shader capabilities. We may want to change that
in the future.

Some fragment pipeline implementations may want to register their own
texture transform handlers.
