		short	ay,
		short *	bx,
		short *	by
	)

Alters bx and by so the (AX,AY)-(BX,BY) segment becomes either horizontal, vertical, 45degrees, or isometrical for pixelart (ie 2:1 ratio)

Set_Pixel_figure()

void Set_Pixel_figure

func

)

All the figure-drawing functions work by calling this function for each pixel to draw.

Before calling these functions, you should assign Pixel_figure depending on what you where you want to draw:

• Pixel_figure_preview : On screen.
• Pixel_figure_preview_xor : On screen, XORing the color.
• Pixel_figure_permanent : On screen and in the image.
• Pixel_figure_clear_preview : On screen, reverting to the image's pixels.
