Enables a visual heatmap that represents overdraw regions.
If the function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code. See DirectComposition Error Codes for a list of error codes.
Heatmaps can be enabled by calling EnableHeatMap. The heatmaps are drawn on the source of the VisualDebug visual and child visuals. The heatmaps are represented in a specified color for all visual content. The heatmap color must have a transparency in order to see the overlaying overdraw regions. The colored surfaces are blended together to visually show all overdraw regions in a single view.
