 You must use [SDL_UnlockTexture](SDL_UnlockTexture)() to unlock the pixels
 and apply any changes.
 
+*Note on SDL_LockTexture vs SDL_UpdateTexture:*
+On the software renderer, you can write directly to the final destination
+with SDL_LockTexture, whereas SDL_UpdateTexture will need to make a copy
+from your buffer to SDL's.
+On the other renderers, it's probably the same (the GLES2 renderer, for
+example, literally just calls SDL_UpdateTexture for its SDL_UnlockTexture
+implementation)... but if you ever need a software renderer, this is the
+thing that would benefit most from texture locking.
+But in real life, with actual GPUs, it doesn't really matter a whole lot.
