Pssibility to set block sizes depends from the choosen driver. For TIFF
you can select stripped or tiled scheme and ajust size of strips or
tiles with the BLOCKXSIZE and BLOCKYSIZE creation options.

It will be something like:

	char **papszOptions = NULL;

	papszOptions = CSLSetNameValue(papszOptions, "TILED", "YES");
	papszOptions = CSLSetNameValue(papszOptions, "BLOCKXSIZE", "256");

	Create(pszName, nXSize, nYSize, nBands, eType, papszOptions);

	CSLDestroy(papszOptions);
