Faster Draw

Oh, more info on beta basic 3.0 here:

Thanks britlion, again.

Effectively, ZX Basic DRAW is faster than BETA BASIC 3.1 one, but slower than 4.x. I will try to improve it. ZX BASIC Draw uses Bresenham's algorithm (the same as circle) wich is quite fast. I will try to examine BETA BASIC 4.x Draw to see what changes.

Regarding to the "STRING" method, this is just a "Polyline Draw", and it will be faster than normal coordinate one, and take less memory: You store each (x, y) pair coordinate in two bytes, and draw from one to another. You can use a string for that (generate cords x, y appending CHR$(x) + CHR$(y) to the string), and later creating an asm routine which traverses the string and call draw subsequently.

I'll see what can I do.
