JPG loader: print error string on failure 
Added error string printing on jpg image loading failure.
The error message help developer find the corrupted jpg file.
Error message is not printed for open from char* data as there the
loaders are tried on by one.

d213a67180 common loader: code refactoring 
Bitmap based pictures doesn't need the viewbox,
LoaderModule should delegate the viewbox to the derived classes which
having vector-based image loaders such as svg, tvg.

In that case, paint resizing can be performed by the loaders by own
policy.

91cf75ff04 jpg_loader JpgLoader: Prevent memory leak 
If the copied data in JpgLoader's data open is invalid,
it is processed without being cleared.
Therefore, data memory free is handled in the destructor.
