Hello , all
i made a decision

I'd like to thank you for your help.

Please, forgive me, if its not your favorite choice.
It is hard to make everyone happy.

So, here the winner:

readPixels_x: "in" x y: "in" y width: "in" width height: "in" height
format: "in" format type: "in" type pixels: "out" pixels
	"This method was automatically generated from OpenGL specs"
	"See http://squeaksource.com/OpenGLSpecs for details"
	<primitive: #primitiveNativeCall module: #NativeBoostPlugin>

	^ self
		glApiCall: #( void glReadPixels ( GLint x , GLint y , GLsizei width
, GLsizei height , GLenum format , GLenum type , GLvoid* pixels ) )
		index: 1334
		attributes: #(
			#category #'VERSION_1_0'
			#version #'1.0'
		)


For 1-arg:

arrayElement: "in" i
	"This method was automatically generated from OpenGL specs"
	"See http://squeaksource.com/OpenGLSpecs for details"
	<primitive: #primitiveNativeCall module: #NativeBoostPlugin>

	^ self
		glApiCall: #( void glArrayElement ( long i ) )
		index: 15
		attributes: #(
			#category #'VERSION_1_1_DEPRECATED'
			#deprecated #'3.1'
			#version #'1.1'
		)
