NOTES



Offer a preference to not create thumbnails in the name of speed
	Accomplish this with special case param of thumb_size = 0 to gm.thumb
	This will still return the date taken but will not actually do the thumbing



In case we ever want to set PROPER EXIF orientation rather than actually rotating pixels,
here is the C code:

long orient = exif["Exif.Image.Orientation"].toLong();
if (1 > orient || 8 < orient) {
	orient = 1;
}
switch (orient) {
	case 1:
		if (90 == degrees) {
			orient = 6;
		} else if (-90 == degrees || 270 == degrees) {
			orient = 8;
		}
	break;
	case 2:
		if (90 == degrees) {
			orient = 5;
		} else if (-90 == degrees || 270 == degrees) {
			orient = 7;
		}
	break;
	case 3:
		if (90 == degrees) {
			orient = 8;
		} else if (-90 == degrees || 270 == degrees) {
			orient = 6;
		}
	break;
	case 4:
		if (90 == degrees) {
			orient = 7;
		} else if (-90 == degrees || 270 == degrees) {
			orient = 5;
		}
	break;
	case 5:
		if (90 == degrees) {
			orient = 4;
		} else if (-90 == degrees || 270 == degrees) {
			orient = 2;
		}
	break;
	case 6:
		if (90 == degrees) {
			orient = 3;
		} else if (-90 == degrees || 270 == degrees) {
			orient = 1;
		}
	break;
	case 7:
		if (90 == degrees) {
			orient = 2;
		} else if (-90 == degrees || 270 == degrees) {
			orient = 4;
		}
	break;
	case 8:
		if (90 == degrees) {
			orient = 1;
		} else if (-90 == degrees || 270 == degrees) {
			orient = 3;
		}
	break;
	default:
	break;
}
exif["Exif.Image.Orientation"] = uint32_t(orient);

cal     : i assume there's a good reason why we can't build the xpcom objects in msys/mingw?
richard : um
richard : i don't think so but i don't completely understand the compatibility issues between binaries out of visual studio and binaries from msys
richard : er, mingw's g++
