Function SDL_RenderTextureAffine 

pub unsafe extern "C" fn SDL_RenderTextureAffine(
    renderer: *mut SDL_Renderer,
    texture: *mut SDL_Texture,
    srcrect: *const SDL_FRect,
    origin: *const SDL_FPoint,
    right: *const SDL_FPoint,
    down: *const SDL_FPoint,
) -> bool

Copy a portion of the source texture to the current rendering target, with affine transform, at subpixel precision.

Parameters

• renderer: the renderer which should copy parts of a texture.
• 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.

Return value

Returns true on success or false on failure; call SDL_GetError() for more information.
