RE: gsapi_ wrappers around the gs_pop_* routines

Hello,

I was wondering what the status is on this patch ? The reason for including
these functions is to have an easy way for users of the API to retrieve a
value from a postscript dictionary.

For example, I use my patched version of Ghostscript as follows:

void RenderEngine::getGhostScriptVariable ( const char * pCommand, const int
nLength, long &rVariable )
	throw ( RenderException )
{
	sendGhostScriptCommand ( pCommand, nLength );
	gsapi_pop_integer ( mpGhostScript, &rVariable );
#ifdef DEBUG_RENDERER
	fprintf ( mpFile, "\npop\n" );
#endif
}

sendGhostScriptCommand just calls gsapi_run_string_with_length to run
'pCommand', which will leave an integer on the stack, which we then pop off
and read with gsapi_pop_integer.

Thanks,

Martin
