SteamVR: Changing SteamVR Compositor's background image will only apply the dominant color of that background instead of the actual background image.

[KWS-Compat]

Changing the SteamVR Compositor's background image will only apply the primary color of that background instead of the actual background image. For instance, if the user applies a background image whose the primary color is red, the compositor's background image will only show a red color overall instead of the actual background image itself (see attachment)

Prerequisite:

• Ensure that SteamVR Home Beta is disabled.

Repro Steps:

1. Launch SteamVR.
2. Open SteamVR Overlay.
3. Navigate to Settings, then 'Customize'
4. On the Background tab, download and apply any background image. Observe that the primary color of the selected background image is applied onto the Compositor's background.

Notes: Issue is only visible while SteamVR Home is disabled, due to the presence of Github #146.

Repro Rate: 5/5

Expected Result: The selected background image to be applied properly and fully onto the compositor environment.

Actual Result: Only the dominant color of the selected background image is applied instead of the actual background image.
