Detailed Description

Using BITMAPINFOHEADER when JPEG2000INFOHEADER or JPEG2000INFOHEADER2 are absent.

We map a new struct MJ2CINFOHEADER on BITMAPINFOHEADER.

This is essentially usefull to add extended information to MJ2C AVI created without the JPEG2000INFOHEADER(2) in the 'strf' chunck.

This way 'old' MJ2C AVI can be patch to support new features like h/w deinterlacing or color correction.

It is resonably safe because we overide elements above which are commonly unused and set to 0

• LONG biXPelsPerMeter;
• LONG biYPelsPerMeter;
• DWORD biClrImportant;
