Can't _fillRect at the far right edge

[MarkJeronimus]

Because of a typo, 1-wide filled rectangles, aligned at the right edge of the clipping window, become invisible:

ESP32_TFT_library/components/tft/tft.c

Line 278 in aa21772

if ((x >= dispWin.x2) || (y > dispWin.y2)) return;

should be

if ((x > dispWin.x2) || (y > dispWin.y2)) return;

Because of this, an image composed of 2x2 rectangles (or larger), scrolling across and beyond the screen, causes artifacts at the right edge.
