GGI_AUTO

If a given ggi_mode is set or checked, any size parameter may be GGI_AUTO (defined in ggi/types.h). It is a placeholder.

When GGI_AUTO is encountered in a parameter, it is replaced with corresponding values specified by GGI_DEFMODE variable.

If the corresponding value is not found in GGI_DEFMODE or that value is also GGI_AUTO, then the driver should select a reasonable value satisfying as many of the given constraints as possible. The following are some recommendations:
