Function ghostty_render_state_update 

pub unsafe extern "C" fn ghostty_render_state_update(
    state: GhosttyRenderState_ptr,
    terminal: GhosttyTerminal_ptr,
) -> GhosttyResult

Update a render state instance from a terminal.

This consumes terminal/screen dirty state in the same way as the internal render state update path.

@param state The render state handle (NULL returns GHOSTTY_INVALID_VALUE) @param terminal The terminal handle to read from (NULL returns GHOSTTY_INVALID_VALUE) @return GHOSTTY_SUCCESS on success, GHOSTTY_INVALID_VALUE if state or terminal is NULL, GHOSTTY_OUT_OF_MEMORY if updating the state requires allocation and that allocation fails
