[sword-devel] Temporarily suspend option filters

[Troy A. Griffitts]

David and Greg,

RenderText can take a buffer to render rather than the current key. 
This is useful for when you grab EntryAttributes from a module and want 
to process them through the same filters for that module.  But this 
won't help turn certain filters on or off temporarily.

It might be interesting to add a return value to the option setter to 
return the current value of the option so you could make 2 less calls, 
but typically, you just make sure the options are off, get your text, 
then turn them back to what they were.

SWBuf fn = mgr.getGlobalOption("Footnotes");
SWBuf xf = mgr.getGlobalOption("Cross-references");
            mgr.setGlobalOption("Footnotes", "Off");
            mgr.setGlobalOption("Cross-references", "Off");

SWBuf text = module.RenderText();

            mgr.setGlobalOption("Footnotes", fn);
            mgr.setGlobalOption("Cross-references", xf);

We could add a flag to RenderText to render with default values for all 
filters, I suppose.  This wouldn't give complete control over what 
options one wanted on or off or whatever other values they should be 
("Secondary Reading", etc.), but might do what we want 80% of the time.

Another _option_ :) (what we do for searching and other such things) is 
to have a second SWMgr for a specific purpose (e.g. popup rendering) 
with filter options set accordingly.  SWMgr instances shouldn't be very 
expensive as our FileMgr is always fully utilized with even just a few 
modules loaded, so the pooled file handlers are already peaked so you 
won't have any more open files.

But basically, in summery, for now, just turn them off temporarily if 
you want them off temporarily :)

	-Troy.
