PARAMETERS
struct aa_hardware_params *p
Hardware parameters structure to alter. It is expected
that this structure only with necessary modifications
will be later used to initialize the AA-lib context.
aa_renderparams *r
Rendering prameters structure to alter. It is expected
that this structure only with necessary modifications
will be later used to render images.
int *argc
Pointer to argc parameter passed to function "main".
char **argv
Pointer to argv parameter passed to function "main".
DESCRIPTION
Use this function to parse the standard command line options used by
AA-lib. Every AA-lib program ought to call this function to let user
specify some extra parameters. The function alters the aa_hardware_params
and aa_renderparams structures and removes known options from the
argc/argv lists. It also parse the AAOPTS environment variable.
When called with NULL for the argc/argv parameters, it parses AAOPTS
only. At least this call ought to be in every AA-lib program.
RETURNS
1 when sucesfull and 0 on failure. The program then can
print the help text available in aa_help variable.
