SDL_LockTexture - Lock a portion of the texture for write-only pixel access.

       This function is available since SDL 3.2.0.

       As an optimization, the pixels made available for editing don't necessarily contain the old texture data.
       This  is a write-only operation, and if you need to keep a copy of the texture data you should do that at
       the application level.

       You must use SDL_UnlockTexture () to unlock the pixels and apply any changes.

texture
              the texture to lock for access, which was created with SDL_TEXTUREACCESS_STREAMING .

       rect   an SDL_Rect
               structure representing the area to lock for access; NULL to lock the entire texture.

       pixels this is filled in with a pointer to the locked pixels, appropriately offset by the locked area.

       pitch  this is filled in with the pitch of the locked pixels; the pitch is  the  length  of  one  row  in
              bytes.

       SDL_LockTexture - Lock a portion of the texture for write-only pixel access.

       Returns true on success or false if the texture is not valid or was not created with

       SDL_TEXTUREACCESS_STREAMING ; call

       SDL_GetError () for more information.
