ITTL

Defines functions specific to transformable tile layers. All transform parameters (A, B, C, D) are 256-based "fractional integers".

interface ITTL {

A short A [@property getter]: Returns the horizontal scaling amount. 256 means no scaling, negative values flip everything horizontally.
A short A [@property setter]: Sets the horizontal scaling amount. 256 means no scaling, negative values flip everything horizontally.
B short B [@property getter]: Returns the shearing amount on the X axis. 256 means one pixel moved downwards for each horizontal scanline.
B short B [@property setter]: Sets the shearing amount on the X axis. 256 means one pixel moved downwards for each horizontal scanline.
C short C [@property getter]: Returns the shearing amount on the Y axis. 256 means one pixel moved right for each vertical scanline.
C short C [@property setter]: Sets the shearing amount on the Y axis. 256 means one pixel moved right for each vertical scanline.
D short D [@property getter]: Returns the vertical scaling amount. 256 means no scaling, negative values flip everything vertically.
D short D [@property setter]: Sets the vertical scaling amount. 256 means no scaling, negative values flip everything vertically.
x_0 short x_0 [@property getter]: Returns the x origin point of the transformation relative to the screen.
x_0 short x_0 [@property setter]: Returns the x origin point of the transformation relative to the screen.
y_0 short y_0 [@property getter]: Returns the y origin point of the transformation relative to the screen.
y_0 short y_0 [@property setter]: Returns the y origin point of the transformation relative to the screen.
