Note: In the following, int indicates that a parameter is truncated
by a function to an integer, or that the return value will always
be an integer. ZScript itself makes no distinction between int and 
float.


========================
--- Global Functions ---
========================

int Rand(int maxvalue)
 * Computes and returns a random integer i such that 0 <= i < maxvalue.
 * The return value is undefined if maxvalue is 0 or negative.

void Quit()
 * Terminates execution of the current script. Does not return.

void Waitframe()
 * Temporarily halts execution of the current script. This function
 * returns at the beginning of the next frame of gameplay. Global 
 * scripts and item pickup scripts only execute for one frame, so in
 * those scripts Waitframe() is essentially Quit().

void Trace(float val)
 * Prints a line containing a string representation of val to 
 * allegro.log. Useful for debugging scripts.

float Sin(int deg)
 * Returns the trigonometric sine of the parameter, which is interpreted
 * as a degree value.

float Cos(int deg)
 * Returns the trigonometric cosine of the parameter, which is
 * interpreted as a degree value.

float Tan(int deg)
 * Returns the trigonometric tangent of the parameter, which is
 * interpreted as a degree value. The return value is undefined if
 * deg is of the form 90 + 180n for an integral value of n.

float RadianSin(float rad)
 * Returns the trigonometric sine of the parameter, which is interpreted
 * as a radian value.

float RadianCos(float rad)
 * Returns the trigonometric cosine of the parameter, which is
 * interpreted as a radian value.

float RadianTan(float rad)
 * Returns the trigonometric tangent of the parameter, which is
 * interpreted as a radian value. The return value is undefined for
 * values of rad near (pi/2) + n*pi, for n an integer.

float Max(float a, float b)
 * Returns the greater of a and b.

float Min(float a, float b)
 * Returns the lesser of a and b.

int Pow(int base, int exp)
 * Returns base^exp. The return value is undefined for base=exp=0. Note
 * also negative values of exp may not be useful, as the return value is
 * truncated to the nearest integer.

int InvPow(int base, int exp)
 * Returns base^(1/exp). The return value is undefined for exp=0, or
 * if exp is even and base is negative. Note also that negative values
 * of exp may not be useful, as the return value is truncated to the
 * nearest integer.

int Factorial(int val)
 * Returns val!. The return value is undefined for val <= 0 (despite the
 * convention 0! = 1.)

float Abs(float val)
 * Return the absolute value of the parameter, if possible. If the
 * absolute value would overflow the parameter, the return value is
 * undefined.

float Sqrt(float val)
 * Computes the square root of the parameter. The return value is
 * undefined for val < 0.

 * The arc is then rotated about the point (rx, ry) using an angle of
 * rangle radians.
 * If closed is true, a line is drawn from the center of the circle to
 * each endpoint of the arc, forming a sector of the circle. If fill
 * is also true, a filled sector is drawn instead.
 * The arc or sector is drawn using the specified index into the entire
 * 256-element palette: for instance, passing in a color of 17 would
 * use color 1 of cset 1.

 * point (rx, ry), using an angle of rangle degrees.
 * The line is drawn using the specified index into the entire

 * Draws a block of tiles on the specified layer of the current screen,
 * starting at (x,y), using the specified cset.
 * Starting with the specified tile, this method copies a block of size
 * blockh x blockw from the tile sheet to the screen. This method's
 * behavior is undefined unless 1 <= blockh, blockw <= 20.
 * The scaling and rotation parameters are reserved for the future, and
 * not currently implemented. This method's behavior is undefined unless
 * rx=ry=rangle=0 and scale=1.
 * Flip specifies how the tiles should be flipped when drawn:

 * 1: Horizontal flip
 * 2: Vertical flip
 * 3: Both (180 degree rotation)

 * (see Counter below) out of the drain counter. Gaining rupees uses the
 * drain counter, for example.
 * is set to Amount when the item is picked up.
 * If Amount & 0x8000 is 0, the counter of this item is increased, if

 * time, the counter's new maximum value is at that time set to the
 * minimum of its current value plus MaxIncrement, Max.
 * If Max is less than the current maximum of the counter, Max is ignored
 * and that maximum is used instead.
 * Notice that as a special case, if Max = MaxIncrement, the counter's
 * maximum value will be forced equal to Max.

int MaxIncrement
 * Corresponds to the "+Max" entry in the Item Editor.
 * In conjunction with Max (see above) this value controls how the
 * maximum value of the counter of this item (see Counter below) is

 * and that maximum is used instead.
