ImPlotPoint getters wrapping

[sonoro1234]

In order to wrap ImPlotPoint *getters returning ImPlotPoint getters https://github.com/cimgui/cimplot/blob/master/generator/cimplot_template.cpp#L9 is done.

Two wrappers are needed for ImPlot_PlotShadedG.

I wonder if there is a simpler way to do it.

I think return pointer to ImPlotPoint it bad decision. How you plane implement getter_funcX?
Only possible way it's store ImPlotPoint in array and return point to data in this array. If you can do this you totally not need ImPlot_PlotLineG and other function just use ImPlot_PlotLine.
ImPlot_PlotLineG main usage it's crate on fly point. But with this syntax it's impossible.

It's must looks like this.

void *(*getter_funcX)(void* data, int idx, ImPlotPoint *point);
void *(*getter_funcX2)(void* data, int idx, ImPlotPoint *point);

ImPlotPoint Wrapper(void* data, int idx)
{
        ImPlotPoint p;
        getter_funcX(data, idx, &p);
	return p;
}

ImPlotPoint Wrapper2(void* data, int idx)
{
        ImPlotPoint p;
	getter_funcX2(data, idx, &p);
	return p;
}

How you plane implement getter_funcX?

In LuaJIT-ImGui:

That mean you always allocate dynamic buffer, what gives huge performance impact. And also this api useless for C code. Only for lua.

Working on this

Thanks.
Just pushed changes.

My question was trying to find a way to avoid two wrappers and having only one.
