[freesci-develop] glutton gfx subsystem

[Matt]

Was talking with Walter about updating the gfx subsystem to support VGA
yesterday, and asked Christoph for his ideas.

<jameson>
The gfx subsystem is fully capable of handling 256 color graphics.
          I'm only 90% sure the resource loaders work, however; and I'm
          pretty sure loading bg pictures will fail.
At any rate, the single biggest issue is that the gfx resource
          loader does not even attempt to load 256 color images; while it's
          supposed to be able to handle different resource loading
          mechanisms, it doesn't get told to use anything other than the old
          16 color stuff ATM.
Try gfx/resource/sci_resmgr.c. The functions in there are the entry
          points called by gfx/resmgr.c whenever it is asked for a graphical
          resource and finds that it's not in its cache. You can either
          multiplex there (depending on SCI version) or wrap that thing up
          into a structure for another level of indirection (which would be
          somewhat cleaner).
It's been a while, so I might be missing something, but I'm pretty
          sure I had 256 color support in mind when I worked on that part of
          the gfx layer.
HOWEVER, I'm not sure how text and primitives drawn by Graph()
          handle their colours. You'll have to ask Lars about that.

Lars, care to comment re: text and Graph()?
