Identifies filtering processes that the hardware should perform when it stretches or shrinks multiplane overlay data.
D3DDDI_MULTIPLANE_OVERLAY_STRETCH_QUALITY_BILINEARWhen the hardware stretches or shrinks the data, it should perform bilinear filtering. If the hardware lacks enough resources to perform bilinear shrinking, the user-mode display driver can use point sampling.
D3DDDI_MULTIPLANE_OVERLAY_STRETCH_QUALITY_HIGHWhen the hardware stretches or shrinks the data, it should perform the highest quality filtering that it supports.
