### fn blitSprite(spriteData: i32, size: i32, x: i32, y: i32, control: i32)
Copies the pixel data at `spriteData` onto the screen at `x`, `y`. The size of the sprite is passed as `width | (height << 16)`.
If the height is given as 0, the sprite is is treated as square (width x width).
The control parameter controls masking and flipping of the sprite:
* bits 0-7: color mask index
* bit 8: switch on masked blit (pixel with color mask index are treated as transparent)
* bit 9: flip sprite x
* bit 10: flip sprite y
