static

Approximates the parameter value for a Bezier curve to get a certain x value Does an iterative DeCasteljau search for the correct value.

^ | C0-------------------------—C1 | / \ | / \ | / \ | P0 P1 | +---------------—atX---------------------------------—>

Parameters

_atX	The X value that the parameter value should be found for
_P0X	The X value of the first key point
_P1X	The X value of the second key point
_C0X	The X value of the first control point
_C1X	The X value of the second control point

Returns: The parameter value that has to be used to get the specified X value
