I just ported my game to love.js (it was a bit tricky because I'm also using fmod), and I noticed that love.resize is not called when the love.js canvas is resized (including when going to fullscreen mode). I have t.window.resizable = true in conf.lua and I tried on chromium and firefox on Linux.
Is this the expected behaviour? This seems to be a similar issue to #33 (I also get blurry fullscreen because love.resize is not called), but my understanding by reading the comments there is that setting t.window.resizable = true should lead to love.resize being called when changing the canvas size.
