 # TODO:
-# 1) -A: render frame #1, render frame #2, ...
-# 2) -s: effects: rotate, smash into bricks, swirl, wave, ...
-# 3) Feature: include ETA @ progress bar
-# 4) Feature: autodetect video width from widest mircart
-# 5) Feature: render mircart as 3D blocks vs flat surface
-# 6) OpenGL: use VAOs + glVertexAttribFormat + glVertexAttribBinding
-# 7) use names @ optdict[] + set from optdefaults
+# 1) -A, -S: replace w/ -s, implement animation script: render frame #1, render frame #2, ...; scrolling script; effects: rotate, smash into bricks, swirl, wave, ...
+# 2) Feature: include ETA(s) @ progress bar(s)
+# 3) Feature: autodetect video width from widest mircart
+# 4) Feature: render mircart as 3D blocks vs flat surface
+
+#
+# 1) Optimisation: speed up ENNToolMiRCARTImporter
+# 2) Cleanup: use names @ optdict + set from optdefaults
+# 3) Feature: scrolling speed as <how many Y units>x<count of frame(s)>
+# 4) Cleanup: use VAOs + glVertexAttribFormat + glVertexAttribBinding
+# 5) Optimisation: split mIRC art into separate VBOs & implement rudimentary culling
+# 6) Optimisation: only call glReadPixels() when changes were made relative to the last call
+# 7) Split video output into separate module, switch to GUI
+# 8) FBOs http://www.songho.ca/opengl/gl_fbo.html
