Eremey Valetov 0d9f29aa7a Fix DRAW M/S/A bugs, add TA rotation, =variable; substitution, X substring execution 
Rewrites gfx_draw() as a recursive draw_engine() to support all DRAW
mini-language features:

Bug fixes:
- M command parsing: skip generic arg parser so M100,50 correctly
  parses both coordinates instead of consuming x as a generic arg
- S (scale) semantics: distance is now (arg ?: 1) * scale / 4, matching
  original GW-BASIC where S4 means 1 pixel per unit, not 4
- A (rotation): implements 90-degree rotation state with direction
  vector transform for all 8 direction commands

New features:
- TA n: arbitrary rotation angle (-360 to 360 degrees) via cos/sin
- =variable;: numeric variable substitution in DRAW strings
- X stringvar;: execute substring from string variable (recursive)
- Scale factor applied to relative M coordinates
