1) Backend: initial optimised cell rendering Python C module implementation skeleton.
2) Backend: raise alpha blending {fore,back}ground colour coefficient to {0.8,1.0 - 0.8}, resp.
3) Backend: reimplement cell rendering using Draw{Rectangle,Text}List().
4) Canvas window: eliminate {canvas,{scroll,tool}bar} flickering during resize.
5) Canvas window: fix cursor artifacts during resizing by masking cursor.
6) Canvas window: restore cursor after executing operations that remove it.
7) Import store: correctly parse non-conforming \u0003,<bg colour> sequences.
8) GUI: correctly save list of recently used files post-update.
