Fix #4954 with perfect screenshots

I tested with this patch and it works perfectly now.

Setting GL_PACK_ALIGNMENT to 1 is the recommended value I found for screenshot.

I choose to store the current GL_PACK_ALIGNMENT value to set it again after the
glReadPixels call even if it seems the value is always 4 because who knows what
value will be set by default in the future.
