You can play with a prototype of the vtm graphical window (gui-bridge branch) on various Windows platforms starting with Win8.1 (including Window Server 2019 Core).

If vtm is launched from a graphical shell, or through the start vtm.exe command, then it automatically turns on the graphical mode.

The vtm server starts in the background, despite the fact that its interface is not yet rendered.

In order to combine the coordinate grid of graphic and text modes, it is necessary, in addition to the integer coordinates of the text cell itself, to add relative fractional coordinates inside the cell in the range [0.0f, 1.0f). In other words, the mouse coordinates when switching from graphic to text mode are converted as follows: fractional_coordinates = cellular_coordinates + (coordinates_inside_the_cell) / cell_size. I think that single precision floating point values ​​should be enough. Now we need to convert all geometric types from int32_t to float32.

This way we will not depend on the cell size and at the same time we will be able to forward the mouse position back to graphic mode if the mouse event was not handled by the text mode.
