#650 TDib does not handle correctly some bitmaps

[Ognyan Chernokozhev]

According to the documentation of BITMAPINFOHEADER, for uncompressed RGB bitmaps the member biSizeImage can be set to 0. But TDib does not handle correctly such bitmaps when they are loaded from a resource. Subsequently, when trying to use such bitmap in a toolbar, only garbage is dsiaplyed.

The problem may be in the ResToMemHandle method, where the bitmap is copied, and the memory size is calculated using that member - and if it is 0, then the bitmap may not be copied correctly.
