Summary0030182: Visualization, Image_AlienPixMap - support reading encoded image from memory buffer
DescriptionCurrently Image_AlienPixMap doesn't provide an interface for reading encoded image from memory buffer - only file name can be given.
At the same time, underlying library (FreeImage) provides such feature.

It is desired extending interface to support this feature.
The most tricky thing would be defining an image format argument - it is undesirable using an enumeration; passing MIME type is desirable, although detecting format from magic header could be even better for formats providing such information (I suppose FreeImage already should support detection in this way).
