273b294d5f o Move the concept of a pin-pulser to a class, so that we can create 
different implementations.

cde792d762 o Make slowdown of GPIO switchable. Make it default off, because the 
old Raspberry Pis should typically do fine (but their performance hurts
  a lot if this is switched on).
o Exposes the setting experimentally added in issue #16 in the Makefile.
o Update README describing what to do in these cases and how to switch
  it on.

5c168a2170 o Use additional GPIO pins on Plus models and Raspberry Pi 2 to 
drive a second parallel chain. 100% more panels for 0% more CPU :)

9c22cf8d2d o Ignore the black time for clocking and use the freedom to use 
shorter PWM base-time. Which then is used for 11 Bit PWM.
o implement CIE1931 luminance correction. Switch on by default.

b1f646057f o Move Canvas into separate file as preparation to be referenced 
in a little graphic primitives library later.
o Rename some methods while they are hopefully still not being used
  to much elsewhere: FillScreen() and ClearScreen() just becomes
  Fill() and Clear(). The affect a Canvas, not necessarily a Screen.
