M4.69: Targa export at 16, 24 or 32 bits per pixel

Browse Source 
document.export {format: "tga"} writes uncompressed true-colour Targa files
through the raster export path (resolution, background, anti-aliasing,
artboard ranges): depth 16 (5-5-5 with a one-bit alpha), 24 (flattened on
white) or 32 (8-bit alpha), rows bottom-up, with the version 2 footer.
Export As offers it with the tgaOptions dialog (Depth).
