Draws a user image around or behind the PSP screen, to fill the black bars on displays whose aspect ratio doesn't match the PSP's (#20325). - Overlays are PNGs in PSP/OVERLAYS. A plain PNG there just works: it's drawn in front of the game, and its transparent hole is found by walking from the image center to each edge until a nearly opaque pixel. Existing RetroArch overlay images can be dropped in as-is. - A subfolder with an overlay.ini can define overlays with a Name, Layer (Foreground/Background) and an explicit Hole=x,y,w,h. - "Load overlay image..." in the display layout screen imports any PNG (including Android content URIs) into the overlays folder and selects it. - The overlay is fit to the screen (aspect preserved, centered). The hole is mapped with the same scale, and the game is fit into it with the normal stretch / integer scale / aspect ratio options. Offset and scale don't apply while an overlay with a hole is active. This goes through CalculateDisplayOutputRect, so touch mapping and post shaders agree. - The selection is a per-orientation, per-game DisplayLayout setting. - Disabled in VR, Cardboard, and with skip buffer effects (except software rendering), since the presentation path doesn't run there.
