 * Layer 0 is the screen itself.

void SetLayerComboI(int layer, int pos, int flag)
 * A shorthand way to set a combo inherent flag on the specified layer.
 * Layer 0 is the screen itself.

int GetLayerComboC(int layer, int pos)
 * A shorthand way to get a combo's CSet on the specified layer.
 * Layer 0 is the screen itself.

void SetLayerComboC(int layer, int pos, int cset)
 * A shorthand way to set a combo's CSet on the specified layer.
 * Layer 0 is the screen itself.

 
bool ChooseB(bool a, bool b)
bool ChooseB(bool a, bool b, bool c)
bool ChooseB(bool a, bool b, bool c, bool d)
bool ChooseB(bool a, bool b, bool c, bool d, bool e)
bool ChooseB(bool a, bool b, bool c, bool d, bool e, bool f)
 * Fairly chooses between two or more boolean values. Overloaded for up to six options.
 
bool ChooseB()
 * Randomly returns true, or false with a 50/50% chance.. 
 
bool RandB()
 * Randomly returns true, or false with a 50/50% chance.
 
bool RandB(int percentTrue)
 * Randomly returns true, or false. uses the input of percentTrue to determine chance.
 * Example: RandB(40) sets a 40% chance of the return being true, and a 60% chance of it being false.

float SafeSqrt(int n, int spec)
 * Returns the square root of n, and returns a specified value 'spec' if n is a negative number.
 * Returns 0 on a failure. 
 
float SafeSqrt(int n)
 * Returns the square root of n, and returns -32768 is the value of n is a negative number.
 * Returns 0 on a failure. 

void SetLinkItem(int itm)
 * Safely sets an item 'itm' true, if it is false, or false if it is true.
 * Will not slow down ZC.
 
void SetLinkItem(int itm, bool state)
 * Safely sets an item 'itm' to the value of 'state'.
 * Will not slow down ZC.
 
void TraceA(int arr)
 * Traces the contents of an array 'arr' to allegro.log. 
 * Warning: This may slow ZC down.

void TraceArray(int arr)
 * Traces the contents of an array 'arr' to allegro.log. 
 * Warning: This may slow ZC down.

void EndFFC(int ffc_ID)
* Terminates an ffc specified by 'ffc_id' and sets all of its values to 0. 

bool InputMiddleClick()
 * Returns true if the middle mouse button is pressed. 
 * Note that not all mice have a middle button. 
  
float BoolToFloat(bool input)
 * Converts variable 'input' to a floating point 1/0 value.
	** Modified from submission by BlueTopHat
 
int BoolToInt(bool input)
 * Converts variable 'input' to a integer (0 or 1).
 
void ScreenToLayer(int sourceMap, int sourceScreen, int layerMin, int layerMax, int drawOpacity, int destLayer){
 * Draws a screen specified by 'sourceMap and sourceScreen;, from layers specified by 'layerMin and layerMax', 
 * at a desired opacity, to the layer specified by 'destLayer' of the current screen.
	** Originally DrawScreenToLayer() - ZoriaRPG
 
int GetLowFloat(int n)
 * Accepts a float as input, and returns the decimal portion as int.
	** Originally GetLowArgument() - Successor, or grayswandir?

int GetHighFloat(int n)
 * Accepts a float as input, and returns the integer portion as int. 
	** Originally GetHighArgument() - Successor, or grayswandir?
 
int GetDigitValue(int n, int place)
 * Extracts a single digit from n at the place specified. 
 * -4 is the ten-thousandTHs place, 0 is the ones spot, and 4 is the ten-thousanDs spot.
	** Originally GetDigit() - Gleeok

int GetPartialValue(int n, int place, int num)
 * Extracts an integer using specific places of any value 'n', from position 'place' plus a number of places 'num'.
	** Originally GetDigit() - Gleeok, or Saffith?

int DecimalToInt(int v)
 * Converts floating point value 'v', after the decimal, to an integer.
	** Originally GetRemainderAsInt() - Gleeok

bool Xor(bool valA, bool valB)
 * Xor comparison of two boolean values. 
 * Returns true if values *do not match*, otherwise false. 
 
bool Collision(npc n) 
bool Collision(ffc f)
bool Collision(item i)
bool Collision(lweapon l)
bool Collision(eweapon e)
 * Shorthand way of doing LinkCollision() and prophylactic against erroneous usage. 
 
float Distance(int x1, int y1, int x2, int y2, int specify_negative_value) 
 * Returns the distance between two sets of coordinates using Pythagoras' Theorem
 * Use specify_negative_value to specify a number to return, if an attempt is made to resolve the square root
   of a negative number. 
   
NoInput(bool analogue_stick)
 * Kill inputs, but not from analogue stock, unless value 'analogue_stick' is set 'true'.
 
 -- Function Changes ( 2.50.2 ) -- 
 ==================================
 
 Distance() now uses SafeSqrt() to avoid errors when parsing negative values, or values too large for ZC 
 to use to perform a square root operation.
