## Description
This PR fixes the black screen shown in emulators across some GL… ES platforms.
The problem is visible during gameplay, when the screen is black. However, when the game is paused and the menu appears, the video is correctly shown under the dialog.
The fix adds a new GLES shader that sets the alpha bits to 0xff, removing transparency issues.
## Motivation and Context
Fixes https://github.com/kodi-game/game.libretro.stella/issues/5 and others.
Addresses the bug mentioned in https://github.com/xbmc/xbmc/pull/15771
## How Has This Been Tested?
Tested using Stella emulator on RPi 3 running LibreELEC.
