Summary0000086: Message-Output / callback on unsupported OpenGL version
DescriptionA customer wish was to react on unsupported OpenGL / OpenGLES version with a default and user-specific message.
We need to implement some kind of callback to handle unsupported versions.

The application should halt instead of trying to instanciate an OpenGL context and throw many exceptions.
TagsNo tags attached.

A callback method was implemented, getting called on initialization, context and shader compilation exceptions.

<code>
program TestProject;

uses
  System.StartUpCopy,
  System.UITypes,
  FMX.Forms,
  FMX.Types3D,
  FMX.Dialogs,
  Gorilla.Context.Types,
  Gorilla.Context.GLES,
  Unit1 in 'Unit1.pas' {Form1};

{$R *.res}

  procedure DoOnGorilla3DError(AContext : TContext3D; AKind : TGorillaContextErrorKind;
    AMsg : String);
  begin
    FMX.Dialogs.MessageDlg(AMsg, TMsgDlgType.mtError, [TMsgDlgBtn.mbOk], 0,
      TMsgDlgBtn.mbOk);
    Halt;
  end;

begin
  // here we declare our individual error callback
  TCustomContextOpenGL.OnError := DoOnGorilla3DError;

  Application.Initialize;
  Application.CreateForm(TForm1, Form1);
  Application.Run;
end.
