Update ToolsVersion in props files
Pull another template variable out, and let the dispatcher handle it.

In preparation for YUV->RGB48 conversion.
dxva2: factor surface dimension alignment factor into a constant.
dxva2: increase surface alignment to 32

Fixes decoding of 720p MPEG-2 samples on Intel GPUs.
dxva2: init the surfaces in black, to avoid "green screen" issues.
Update ffmpeg
More complete check if the pixel conversion buffer exists.
Fixed broken aspect ratios when processing raw video with negative height (ie. RGB)
Enable support for "demuxing" AviSynth scripts
Fix registration of AviSynth scripts in the installer
avcodec: ref the frame before copying pointers in case the data is copied.
Fix copying of packed image buffers
Fix format number in the installer
Update ffmpeg
dxva2: Factor aligning of the dimension into a function
dxva2: reduce base alignment back to 16, and only increase MPEG-2 to 32.
Rename function arguments to be clearer on what they actually are
Allow the timer macros to be used in release builds
Use 64 byte aligned memory for frame buffers
dxva2cb: disable frame queue for Intel GPUs

The frame queue reduces performance on Intel systems instead of increasing it.
This boosts Copy-Back performance by 100-150% on various clips.
