Hmm. Shouldn't be doing that. Make sure you're calling pgContextUpdate() to have it
update the screen. If you still have problems, let me know how I can reproduce them
and I'll take a look.

Oh. There was supposed to be a pgSetFont primitive :)
Must have added it to the server but not PGFX.
I just added the missing pgSet* functions to the PGFX code in CVS. This includes
pgSetFont, pgSetMapping, and pgSetLgop. pgSetLgop will do the XOR, AND, and OR
operations you need (plus many others). pgSetMapping might be helpful for scaling a
virtual coordinate system to whatever size the canvas is. For example, to scale a
160x160 virtual screen to the canvas, call this before drawing:
pgSetMapping(context,0,0,160,160,PG_MAP_SCALE);
Note that the pgSet* functions are primitives too. ('nonvisual' primitives) so they go
by the same rules. if you call it with an immediate context, it will have effect only
until the screen is updated with the primitives in the buffer. If it is calles with a
persistent context, it will always have effect. (Well, unless it is deleted)

Well, this should fix that too :)
