### Added
- Support for ftdi chip based LED-devices with ws2812, sk6812 apa102 LED types (Many thanks to @nurikk) (#1746)
- Support gaps on Matrix Layout (#1696)
- Windows: Added a new grabber that uses the DXGI DDA (Desktop Duplication API). This has much better performance than the DX grabber as it does more of its work on the GPU.

From the data sheet:
(TH+TL=1.25μs±600ns)
T0H, 0 code, high level time, 0.40µs ±0.150ns
T0L, 0 code, low level time, 0.85µs ±0.150ns
T1H, 1 code, high level time, 0.80µs ±0.150ns
T1L, 1 code, low level time, 0.45µs ±0.150ns
WT, Wait for the processing time, NA
Trst, Reset code,low level time, 50µs (not anymore... need 300uS for latest revision)
To normalise the pulse times so they fit in 4 SPI bits:
On the assumption that the "low" time doesnt matter much
A SPI bit time of 0.40uS = 2.5 Mbit/sec
T0 is sent as 1000
T1 is sent as 1100
With a bit of excel testing, we can work out the maximum and minimum speeds:
2106000 MIN
2590500 AVG
3075000 MAX
Wait time:
Not Applicable for WS2812
Reset time:
using the max of 3075000, the bit time is 0.325
Reset time is 300uS = 923 bits = 116 bytes
