SOIL Great little image loading library

After messing around with dds textures for far too long I found SOIL. Simple OpenGL image loading library, and it is.

	int channels = 0;
	unsigned char* image = SOIL_load_image
	(
		filename,
		&width, &height, &channels,
		SOIL_LOAD_AUTO
	);

	if(image == NULL)
	{
		isLoaded = false;
		return;
	}

	GLuint tex_2d =SOIL_create_OGL_texture
	(
		image,
		width, height, channels,
	 	SOIL_CREATE_NEW_ID,
	 	SOIL_FLAG_MIPMAPS | SOIL_FLAG_INVERT_Y | SOIL_FLAG_NTSC_SAFE_RGB | SOIL_FLAG_COMPRESS_TO_DXT
	);

	SOIL_free_image_data
	(
		image
	);

My use case is a little more complicated than the examples on the page but only because I wanted the height and width info. This handles the OpenGL Y inversion problem and dds files that have no mip maps which were the ones I was testing with.

Very nice and easy to add statically.

Also while I was debugging my problem I noticed gDebugger is now free and it works very nicely.
