Crust: Using either a food processor or a mixer combine the confectioners' sugar, flour, and butter, until its a dough consistency. With your fingers, press the dough into the tart pan and push the crust into the indentations in the sides. Pat until the crust is even. Bake for 10 to 12 minutes, at 350 degrees until very lightly browned. Set aside to cool. They should be cool and firm before removing from the tart pan.
Slice the fruit as desired for design
Preparing the filling: Beat the cream cheese, sugar, and vanilla together until smooth. Spread over the cooled crust. Arrange the sliced fruit over the cream filling
Glaze: Combine the limeade, cornstarch, lime juice, and sugar in a small saucepan and cook over medium heat until clear and thick, about 2 minutes. Let cool. With a pastry brush, glaze the entire tart. There will be a lot of extra glaze.
