/****** SASA Picture Class Template **********************

Currently there are two types of this object

ST_RGBM		- CSTPic<uc_pixel>	- UCHAR r,g,b,m channels</uc_pixel>

ST_RGBM64	- CSTPic<us_pixel>	- USHORT r,g,b,m channels</us_pixel>

The CMAP RASTER pictures have to be converted to ST_RGBM or 

ST_RGBM64, but the CMAP information can be used with the help 

of m_raster.  

m_lX,m_lY - the length of the picture in X,Y direction

m_pic - the buffer of the picture

m_ras - stores the pointer to the original RASTER picture
