7 years agoFix copy icon background ordering

Fix copy icon background ordering

I had this working, then sorted the properties, which made it stop
working, because `background` is a shorthand form, and when it came
after the other `background-*` properties in the list it effectively
overrode them.

Make it `background-image` instead, so it doesn't override, and is
immune to sorting vagaries.

Avoid unnecessary base conversions

Instead of converting to a canonical hexadecimal base format, let the
updating component juts pass back the raw value + base. This should cut
the number of conversions by about 25%. For example, if I change the
binary field, instead of converting to hexadecimal once, then from
hexadecimal to some other base for three of the four fields (ie. four
total conversions), we instead just convert three fields.

7 years agoSpeed up multiplyDigits
Greg Hurrell [Sat, 1 Aug 2015 00:56:43 +0000 (17:56 -0700)] 
Speed up multiplyDigits

If we can double the length of the result in a single operation, we do.
This makes us faster for larger multipliers.

Note that I could make this even faster for really big multipliers by
employing some kind of memoization:

eg. multiply X by 1000:

  - iteration 0: X + X (2X)
  - iteration 1: 2X + 2X (4X)
  - iteration 2: 4x + 4X (8X)
  - iteration 3: 8X + 8X (16X)
  - iteration 4: 16x + 16X (32X)
  - iteration 5: 32X + 32X (64X)
  - iteration 6: 64X + 64X (128X)
  - iteration 7: 128X + 128X (256X)
  - iteration 8: 256X + 256X (512X)
  - iteration 9: 512X + 256X (768X) [use largest possible prev value)
  - iteration 10: 768X + 128X (896X) [largest possible is smaller now)
  - iteration 11: 896X + 64X (960X) [and smaller]
  - iteration 12: 960X + 32X (992X) [smaller]
  - iteration 13: 992X + 8X (1000X) [smaller still; note skip as well]

This might be hard to implement though. I was thinking it might call for
a heap but I don't think so; it just needs a stack, and we pop off until
we get a usable value from it.
