- A few notes.
-
- This is the library (and source) I have developed in the process of writing
- several BGI drivers. It includes several example drivers and whatever other
- drivers I've been able to find. I've not included an e-mail address since
- the one I've got won't be valid for much longer. Feel free to use the
- regular mails.
-
- There appears to be a bug in the fillpoly routines in the BGI kernal.
- Occasionally a polygon will be outlined but not filled. I've only seen it
- during the drawing of random polygons in the bgidemo so I haven't managed to
- pin down the circumstances yet.
-
- I've just started using TD 2.0. With the new version of the debugger it
- is possible to symbolically debug a BGI driver. More on this in a later
- release.
-
-
- Let me know what you think.

- UPDATES FROM LAST RELEASE:
-
- A bug was reported in save/restore bitmap. Turned out I was saving
- and restoring one line too many. Fixed.
- Two new drivers have been added.
- A major bug was found and fixed. The unitialised data segment was
- not being added to the driver. Could have been fixed by using a
- linker option but I reordered the segments to provide a more failsafe
- solution (one that didn't require remembering strange options).
- The drivers and library have been recompiled using Turbo C++.
