0030182: Visualization, Image_AlienPixMap - support reading encoded image from memory buffer

Added two new Image_AlienPixMap::Load() methods, taking std::istream
and memory buffer (pointer, length) arguments.
This allows reading image from application memory or from file with non-zero offset.

Added Image_AlienPixMap::IsTopDownDefault() static property allowing to query rows order used by linked image library,
so that application might generate UV texture coordinates accordingly.

Added missing Release() to IWICImagingFactory instance.
