VideoCapture/DSHOW : Allow to set CAP_PROP_CONVERT_RGB before FOURCC/FPS/CHANNEL/WIDTH/HEIGHT. * 🐛 cap_dshow : Allow to set CAP_PROP_CONVERT_RGB before FOURCC/FPS/CHANNEL * 🐛 cap_dshow : fix g_VI.setConvertRGB not being called with correct boolean value on first property set. * ✅ cap_dshow : Test CAP_PROP_CONVERT_RGB persistence * 🚨 Fix cast from bool to double * 🚨 Fix trailing whitespace
