add a display command.

[rminnich]

The display command uses the plan9ports devdraw device, and the 9fans devdraw Go support, to allow a display of the state of the buffer.

Currently, a user can do something like this:

Set up so devdraw command is in $PATH

PLAN9=/Users/rminnich/Documents/plan9 export PLAN9 PATH=$PATH:$PLAN9/bin export PATH

Now run utk

utk ~/Downloads/SBIOS_P5043_PG535_SKU_893_02.02.03_rel_prod.rom
display start
remove_dxes_except list
display end

The result will be two windows, one showing before, and one after.

The plan is that this can get fancier:

utk ~/Downloads/SBIOS_P5043_PG535_SKU_893_02.02.03_rel_prod.rom
display start
remove Http.*
display nohttp
remove_dxes_except list
display end

Also, note, although we only set up one pixel for each point, devdraw is nice to you: if you grow the window it grows the display of ROM. Also, the border is necessery for OSX with its rounded edges.

And, yeah, note, they all look the same. Still not sure why.

Can you dump the intermediate states to files and just diff?

[orangecms]

just tried this myself, with an empty list, expecting all the DXEs to go down the drain - which should result in a big change, but it looks the same

@rminnich here is a fixup for the rendering rminnich#1

[orangecms]

it looks like the issue is with the remove_dxes_except command - with just a simple remove, I do see a difference now!
