qtharts OpenGL ES

As I wrote, qtcharts cannot use OpenGL ES, only OpenGL. True way is switch qtcharts to use OpenGL ES, but now qtcharts from git supports no OpenGL mode, but when I configure my Qt6 from git with -opengl es2 flag, qtcharts wants OpenGL.

The stupid way is if there is opengl es2 flag so in charts.pro and DEFINES += QT_NO_OPENGL

So no more OpenGL in qtcharts. But it is not all.

In qxymodelmapper in QXYModelMapperPrivate::valueFromModel code

return QDateTime(value.toDate()).toMSecsSinceEpoch();

error no matching conversion for functional-style cast from QDate to QDateTime

Also this is qxyseries.h

void replace(QList<QPointF> points);
void replace(QVector<QPointF> points);

error cast member cannon be redeclared

And there are a lot of warnings in qtcharts from clang.

P.S. Please do qtcharts with LGPL.
