The test program and test filter wasn't working properly because the ID
for it had actually changed.
The test programs also weren't updated for the new main render callbacks
which must be used when making a program.
- Implement windows monitor capture (code is so much cleaner than in
OBS1). Will implement duplication capture later
- Add GDI texture support to d3d11 graphics library
- Fix precision issue with sleep timing, you have to call
timeBeginPeriod otherwise windows sleep will be totally erratic.
