inno setup - How to display a larger license box in an InnoSetup installer?

Question

InnoSetup by default displays the license agreement in a really tiny text area that the user can't make bigger in any way.

While I know most people don't read these, I feel that providing it in a format that makes it particularly hard to read is a bad idea, and might form part of a defense in court.

Is there any way in InnoSetup to display the license in a large separate window? A pre-rolled Pascal script perhaps?

You can change the WizardForm size and rearrange the controls in it if you want to make it bigger. I made this example to show you how to change the form height for the License page.

[Setup]
AppName=StackOverflow large license box
AppVersion=1.0
CreateAppDir=no
DisableProgramGroupPage=yes
DefaultGroupName=My Program
UninstallDisplayIcon={app}MyProg.exe
LicenseFile=license.txt
;OutputDir=userdocs:Inno Setup Examples Output

[Code]

var
  DefaultTop, 
  DefaultLeft, 
  DefaultHeight,
  DefaultBackTop, 
  DefaultNextTop, 
  DefaultCancelTop,
  DefaultBevelTop, 
  DefaultOuterHeight: Integer;

const 
  LicenseHeight = 600;

procedure InitializeWizard();
begin
  DefaultTop := WizardForm.Top;
  DefaultLeft := WizardForm.Left;
  DefaultHeight := WizardForm.Height;
  DefaultBackTop := WizardForm.BackButton.Top;
  DefaultNextTop := WizardForm.NextButton.Top;
  DefaultCancelTop := WizardForm.CancelButton.Top;
  DefaultBevelTop := WizardForm.Bevel.Top;
  DefaultOuterHeight := WizardForm.OuterNotebook.Height;

  WizardForm.InnerPage.Height := WizardForm.InnerPage.Height + (LicenseHeight - DefaultHeight);
  WizardForm.InnerNotebook.Height :=  WizardForm.InnerNotebook.Height + (LicenseHeight - DefaultHeight);
  WizardForm.LicensePage.Height := WizardForm.LicensePage.Height + (LicenseHeight - DefaultHeight);
  WizardForm.LicenseMemo.Height := WizardForm.LicenseMemo.Height + (LicenseHeight - DefaultHeight);
  WizardForm.LicenseNotAcceptedRadio.Top := WizardForm.LicenseNotAcceptedRadio.Top + (LicenseHeight - DefaultHeight);
  WizardForm.LicenseAcceptedRadio.Top := WizardForm.LicenseAcceptedRadio.Top + (LicenseHeight - DefaultHeight);

end;

procedure CurPageChanged(CurPageID: Integer);
begin
  if CurPageID = wpLicense then
  begin
    WizardForm.Top := DefaultTop - (LicenseHeight - DefaultHeight) div 2;
    WizardForm.Height := LicenseHeight;
    WizardForm.OuterNotebook.Height := WizardForm.OuterNotebook.Height + (LicenseHeight - DefaultHeight);
    WizardForm.CancelButton.Top := DefaultCancelTop + (LicenseHeight - DefaultHeight);
    WizardForm.NextButton.Top := DefaultNextTop + (LicenseHeight - DefaultHeight);
    WizardForm.BackButton.Top := DefaultBackTop + (LicenseHeight - DefaultHeight);
    WizardForm.Bevel.Top := DefaultBevelTop + (LicenseHeight - DefaultHeight);
  end
  else 
  begin
    WizardForm.Top := DefaultTop;
    WizardForm.Left := DefaultLeft;
    WizardForm.Height := DefaultHeight;
    WizardForm.OuterNotebook.Height := DefaultOuterHeight;
    WizardForm.CancelButton.Top := DefaultCancelTop;
    WizardForm.NextButton.Top := DefaultNextTop;
    WizardForm.BackButton.Top := DefaultBackTop;
    WizardForm.Bevel.Top := DefaultBevelTop;
  end;
end;

Copy it to a new iss file and provide a valid license.txt file in order to compile successfully. The script is tested with inno 5.4.0 but it should work with any 5.x.
