Haihao Xiang	55ceddff91	vaapioverlay: inline sinkpad scaling support ... Often, users will need to scale inputs (e.g. with vaapipostproc) before they are submitted to the vaapioverlay. However, this results in multiple VPP passes/operations in the pipeline which creates unnecessary process overhead. This change allows for inputs to be submitted at original scale to vaapioverlay with per-sinkpad scale dimensions specified so they can be scaled and blended/composited in a single VPP pass/operation to avoid the unnecessary process overhead.

U. Artie Eoff	48b6404f8e	vaapioverlay: use vpp blend state iif using alpha ... Don't set VAAPI vpp blend flags if alpha == 1.0, i.e. fully opaque. This can avoid extra processing overhead on some drivers that apply blending unconditionally when flags are present, even if the end result is the same without blend flags (i.e. all opaque alpha channels).
