- texture
the source texture.
- srcrect
a pointer to the source rectangle, or NULL for the entire texture.
- origin
a pointer to a point indicating where the top-left corner of srcrect should be mapped to, or NULL for the rendering target's origin.
- right
a pointer to a point indicating where the top-right corner of srcrect should be mapped to, or NULL for the rendering target's top-right corner.
- down
a pointer to a point indicating where the bottom-left corner of srcrect should be mapped to, or NULL for the rendering target's bottom-left corner.
