Internal rendering functions
----------------------------

1. Ellipse rendering is done using a new floating point DDA algorithm
   to avoid the overflow problems the old integer algorithm had. The
   ellipse code needs to be re-engineered with a new integer algorithm
   that wont sufffer from overflow.

   All the ellipse assembler functions are currently stubbed out and
   the emulated floating point routine is used. Although this routine
   is fast, the assembler integer routines would be faster if they were
   fixed.

Microsoft Visual C++ 5.0 32-bit Windows support
-----------------------------------------------

1. The sample programs compiled fine from the command line with this
   compiler, however when the samples were runs that displayed a dialog
   box (such as the Game Framework BOUNCE program), the main dialog
   box never came back. This behaviour is strange and I dont recall this
   happening with the 4.2 version of the compiler. It is also strange
   because both Borland C++ 4.52 and Watcom C++ 10.6 and 11.0 all run
   these programs properly.

   I have not tried this building the program from an IDE file, so it
   could be something related to the command line build process.
