Lucy2003 9393f05fdc Add support for using 4bits mode smooth fonts ... By default,the create_font create a 8 bits/pixel fonts,but now it can be transform into 4 bits/pixel and used on ESP8266/ESP32.I have tested it on ESP32,both SPIFFS and flash array. Main modifications : 1. add readInt16() and readInt8() functions; 2. add a flag c4bpp to struct gFont. 3. adjust 4bits mode display. 4. add a tool made by pure C to convert font files. The API is compatible with previous.Compressed font format is described in tools/create_smooth_font/compress_font/readme.md Signed-off-by: Lucy2003 <53362310+Lucy2003@users.noreply.github.com>		2021-07-16 13:15:13 +08:00
