Patterns and textures
void	MakeTexture (unsigned short int tex_ind, unsigned short int *&fig)
	bind a texture defined by 2 bytes per pixel array to an index
void	MakeTexture (unsigned short int tex_ind, unsigned char *&fig)
	bind a texture defined by 1 byte per pixel array to an index
void	MakeTextureResident (unsigned short int tex_ind)
	make a texture is resident (saved in video-memory) before showing for the first time (Linux only)
void	MakeTexturesResident (int n, unsigned short int *tex_ind)
	make textures in an array resident (saved in video-memory) before showing it for the first time (Linux only)
void	QueryTextureResidency (unsigned short int tex_ind)
	query if a texture is resident (saved in video-memory)
void	QueryTexturesResidency (int n, unsigned short int *tex_ind)
	query if textures in an array are resident (saved in video-memory)
void	MakePattern (double width, double height, double f(double x, double y), double contrR, double contrG, double contrB, double *&fig)
	create a colored pixmap with and arbitrary pattern defined by f
void	MakePattern (double width, double height, double f(double x, double y), double l, double *&fig)
	create a grayscale pixmap with and arbitrary pattern defined by f
void	MakePattern (double width, double height, double f(double x, double y), double contrR, double contrG, double contrB, unsigned short ind)
	create an arbitrary colored pattern defined by f stored in video memory
void	MakePattern (double width, double height, double f(double x, double y), double l, unsigned short ind)
	create an arbitrary grayscale pattern defined by f stored in video memory

Function Documentation

void MakePattern	(	double	width,
		double	height,
		double	fdouble x, double y,
		double	contrR,
		double	contrG,
		double	contrB,
		double *&	fig
	)

This function creates a color pattern defined by function f(x, y). This function should return float number within [-1 1] range, which corresponds to [-100% +100%] contrast range. Values less than -1 or larger than 1 will be displayed as transparent.
