Code that seems to be dead/old.

I'm trying to modify Milton to add grid tool for handmade hero to draw pixel-grid.

I found things that seem old/dead code. I'll list them just in case I'm missing something important.

• https://github.com/serge-rgb/milton/blob/e369c5eaeb12deabad5af9e86b78023f9a693210/src/gui.cc#L303-L304

• https://github.com/serge-rgb/milton/blob/e369c5eaeb12deabad5af9e86b78023f9a693210/src/gui.cc#L311-L312

• The following line is redundant because copy_stroke does copy the brush. https://github.com/serge-rgb/milton/blob/e369c5eaeb12deabad5af9e86b78023f9a693210/src/milton.cc#L1506

• Why calculating the BB of the stroke twice then union them? https://github.com/serge-rgb/milton/blob/e369c5eaeb12deabad5af9e86b78023f9a693210/src/milton.cc#L1508-L1509
