Logic error in esUtil.h - Easy Fix

[SirGouki]

I was typing up esUtil.h on my raspberry pi, and I noticed the following

opengles3-book/Common/Include/esUtil.h

Lines 184 to 185 in 423d936

	void ESUTIL_API esRegisterKeyFunc ( ESContext *esContext,
	void ( ESCALLBACK *drawFunc ) ( ESContext *, unsigned char, int, int ) );

The function here incorrectly takes in void(ESCALLBACK *drawFunc)(ESContext *, unsigned char, int, int). This should be the following, instead:

void ESUTIL_API esRegisterKeyFunc ( ESContext *esContext, 
                                     void ( ESCALLBACK *keyFunc ) ( ESContext *, unsigned char, int, int ) );

Oddly enough, the documentation comment shows the correct keyFunc parameter:

opengles3-book/Common/Include/esUtil.h

Lines 179 to 183 in 423d936

	//
	/// \brief Register a keyboard input processing callback function
	/// \param esContext Application context
	/// \param keyFunc Key callback function for application processing of keyboard input
	//
