 * GLFW & OpenGL
 * Better cross platform support (ie. windows)
 
+## Remaining work before mergin this branch
+This section exists to provide an overview of the tasks that needs to be done
+before merging the glfw branch back into master.
+* [x] Batch rendering
+  + Adding models now requires a transform.
+  + We require `renderbatch_refresh` to finalize the renderobj buffer.
+  + Still require `RenderObject_new` in the end, to make the buffers.
+  + [ ] We also want enable the user to automatically generate IBO, by exposing
+    some API call.
+  + [ ] Should make a "`renderbatch_update_renderobject`" API, that uploads
+    all the changed vertex data, possibly by using a `.dirty` flag.
+  + [ ] Merge textures from RenderObjects into texture atlas
+* [ ] (auto?) Index buffers
+  + [ ] Missing IBO generation, should be easy,
+    ```
+    vertices[n][3]f32 |> sort (
+      \original_idx pos_vec3 -> ({x,y,z}, original_idx) /* or possibly by morton codes/z-ordering */
+    ) vertices |> sort-by-original_idx
+    ```
+  + [ ] Should also be possible with `assimp`
+* [ ] Model loading of some sort
+  + [ ] Should also be possible with `assimp`
+* Revise rendering pipeline.
+  + [ ] We should not rely on a single global `drawcalls` variable, instead we
+    should render to textures and present those instead.
+    - [ ] These should be resized with the window
+  + [ ] Should be passed as parameter. _we want to completely get rid of
+    `GLOBAL_PLATFORM`_
