[dvipdfmx] pdf:page , pdf:direct

[Alexander Grahn]

Dear all,

both specials were added in rev. 53691 around six weeks ago, but current
xdvipdfmx as of 20200315 refuses to process them.

With this example input

test%
\special{pdf:page 0 0 m 50 50 l S}%
\special{pdf:direct 0 0 m 50 50 l S}%
test
\bye

one gets

dvipdfmx:warning: >> xxx "pdf:page 0 0 m 50 50 l S"
dvipdfmx:warning: >> Reading special command stopped around >> 0 0 m 50 50 l S<<
dvipdfmx:warning: >> xxx "pdf:direct 0 0 m 50 50 l S"
dvipdfmx:warning: >> Reading special command stopped around >> 0 0 m 50 50 l S<<

Are the specials, perhaps, incorrectly used?

Kind regards, Alexander
