* This program is based on the popular DKB raytracer version 2.12.
* DKBTrace was originally written by David K. Buck.
* DKBTrace Ver 2.0-2.12 were written by David K. Buck & Aaron A. Collins.

/* Below are several defines needed by the generic parts of POV. You
* may redefine them as needed in this config.h file.
*
* The following constants are needed by various POV modules. Each has
* a default (shown below) which is will be defined in frame.h if you don't
* define them here.
*
* #define EPSILON 1.0e-10 - a small value used for POLY
* #define FILE_NAME_LENGTH 150 - default file name length
* #define HUGE_VAL 1.0e+17 - a really big number
* #define DBL_FORMAT_STRING "%lf" - the string to use for scanfs of doubles
* #define DEFAULT_OUTPUT_FORMAT 'd' - the default +f format
* #define RED_RAW_FILE_EXTENSION ".red" - for +fr, this is the extension for the
* red file
* #define GREEN_RAW_FILE_EXTENSION ".grn" - ditto for the green file
* #define BLUE_RAW_FILE_EXTENSION ".blu" - ditto again for the blue file
* #define FILENAME_SEPARATOR "/" - the character that separates names
* in a path.
* #define CASE_SENSITIVE_DEFAULT 2 - controls case sensitivity in DAT files
* #define READ_FILE_STRING "rb" - special binary (raw, uncooked)
* #define WRITE_FILE_STRING "wb" modes of fopen()
* #define APPEND_FILE_STRING "ab"
* #define NORMAL '0' - machine-specific PaletteOption settings
* #define GREY 'G'
*
* These routines are required by POV to compute trace times. The defaults
* shown below are defined in most versions of C. You may redefine them if
* your compiler doesn't support these. If time is completely unsupported
* define them as 0.
*
* #define START_TIME time(&tstart);
* #define STOP_TIME time(&tstop);
* #define TIME_ELAPSED difftime (tstop, tstart);
*
* Note difftime can be replaced with: #define TIME_ELAPSED (tstop - tstart);
* in some cases.
*
* These are optional routines that POV calls. You may define them
* or if undefined they will be defined as empty in frame.h.
*
* #define STARTUP_POVRAY - first executable statement of main
* (useful for initialization)
* #define PRINT_OTHER_CREDITS - used for people who extend the machine specific modules
* (put your own printf's here)
* #define TEST_ABORT - code to test for ^C or abort
* (called on each pixel)
* #define FINISH_POVRAY - last statement before exiting normally
* #define COOPERATE - called for multi-tasking
*
* These items are standard on some C compilers. If they are not defined
* on your compiler or are called something different you may define your
* own or use the defaults supplied in frame.h as shown below.
*
* #define DBL double - floating point precision
* #define ACOS acos - arc cosine of DBL
* #define SQRT sqrt - square root of DBL
* #define POW pow - x to the y power - x, y DBL
* #define COS cos - cosine of DBL
* #define SIN sin - sine of DBL
* #define labs(x) (long) ((x<0)?-x:x) - Returns the absolute value of long integer x
* #define max (x,y) ((x<y)?y:x) - greater of x and y
*
* On some systems "sprintf" returns the string rather than the length
* of the string. If the string is returned, define the following:
* #define STRLN(x) strlen(x)
*
* #define setvbuf(w,x,y,z) - some systems don't understand setvbuf.
* If not, just define it away - it's
* not critical to the raytracer. It
* just buffers disk accesses.
* This macro controls prototyping and is required by POV. Choose one
* of the two options below or if left undefined it will default to ANSI
* in frame.h
*
* #define PARAMS (x) x - do ANSI prototyping
* #define PARAMS (x) () - do K&R non-ANSI prototyping
*
* These allow command line vs non-command line versions and alternate
* main routines. Normally they should be undefined. Define them 1 if needed.
* #define ALTMAIN 1
* #define NOCMDLINE 1
