This particular display has a design error! The controller has 3 pins to configure to constrain
the memory and resolution to a fixed dimension (in that case 128x128) but they leaved those pins
configured for 128x160 so there was several pixel memory addressing problems.
I solved by setup several parameters that dinamically fix the resolution as needit so below
the parameters for this diplay. If you have a strain or a correct display (can happen with chinese)
you can copy those parameters and create setup for different displays.

    Note 1: The __144_RED_PCB__ display has hardware addressing of 128 x 160
    but the tft resolution it's 128 x 128 so the dram should be set correctly
