textInit() for font. add variable so shinku() knows what page we're on.

modex draw char use rom font height, do not assume 8.

fix updated code to copy the char, not NUL char (doh!)
fix modex VGA init to set .width and .height page members.
shinku()'s fps indicator works now!

save/restore AX/BX when calling BIOS to get ROM font.

shinku() needs ROM font to modexprint. make sure to fetch it.

replace inline asm with _fmemcpy to copy ROM font char.
add reminder that it might be faster for modexDrawChar to point
directly at ROM font char.

the reason for replacing the inline assembly is that the original
code acted without saving/restoring CPU registers that the C compiler
optimization stage assumes holds results from previous C compiler
generated code. corruptiong the optimizer's expectations is the reason
why all code using modex (and assuming things about DS and ES) is the
reason all game code was blowing up. this fix makes things stable again.

repo sync and i did some debugging ww

remove wraparound check in modex print, add addr adjust for newline.
FONTGFX.EXE now prints the ascii rose in mode X, though the ASCII art
is too wide for 320x240 mode.

now it works without crashing.

clear video RAM using pointer set after INT 10h + vga update, not
before. this fixes scribbling over VGA ROM BIOS and possible DOSBox
UMB corruption.

modex mode 1 is 320x240 so make sure it's 320 across.

let's show Sparky4 what I mean by vertical column font rendering. Repo sync.

this code should demonstrate what I mean about minimizing our writes to
the map mask register and using arithmetic to step from byte to byte.
at least in DOSBox-X, the characters appear much faster now.

don't use printf. use modexprint. explain why. fontgfx shows grid of
font chars correctly now. not sure what the long pause at startup is.

font fack!
