Feb 25, 1991 STK Version 1.1 Released
--------------------------------------
- Added gr_setvisualpage and gr_setactivepage. These should be used
instead of the BGI functions, since these set the variables
gr_visualpage and gr_activepage which are used by other gr functions.
- Added GR_MODE_CLEAR_FAST text writing mode. This mode uses the
fixed 8x8 character set from ROM and writes directly into screen
memory. It restricts writing to byte resolution in X direction and it
works only in those modes supported by the sprite routines, but it
several times faster than GR_MODE_CLEAR.
- Corrected error with va_start usage in several functions
- The sources can be compiled with Turbo C++ 1.0, too.
- spr_regulate_speed now uses timer interrupt to regulate the speed
to exactly 18.2 frames per second (provided that the machine is fast
enough!)
- Documentation divided into two files: STK.DOC gives genereal
information and STKREF.DOC is a reference to the functions.
- StarMines extended: background stars, several new alien types, hall
of fame, bug fixes, cheat mode.
- SPRDEMO demonstration program added.
- The functions can be used in the color EGA mode, too, but only
black and white sprites are supported. If you have a multicolored
background it is not preserved when the sprites moves over it.
- SPR and SPR_HIT functions check the SPRITE arguments and call
spr_err if they are invalid.
- Some new gr_printf functions added.
- Load/save filenames are now echoed correctly in SPRED.
