Fix warnings about "conversion to a greater size" that appear in VS2015 in x64 with /W4.

Browse Source 
The warning concerns the return value of stbi_err, which is an int, being converted to a pointer. In VS2015 it seems casting directly from a 32-bit int to a 64-bit pointer triggers this warning. Worked around by first converting to a 64-bit int (here size_t) and then to a pointer.
