Fork of SPI_TFT by Peter Drescher

See Components - RA8875 Based Display

Enhanced touch-screen support - where it previous supported both the Resistive Touch and Capacitive Touch based on the FT5206 Touch Controller, now it also has support for the GSL1680 Touch Controller.

Updated some data types to more consistently use loc_t and dim_t.

; Added a booleanStream api which is handy for soft fonts. It takes a pixel stream and translates it to forecolor and backcolor.
