Matthijs Kooijman 5cdd09dfa6 Issue #340, add cimg_annotate_screenshot example 
CImg is a lightweight, header-only image processing library. The
makefile automatically makes a git clone of this library when building.

This example shows how to capture a screenshot using the bitmap device,
convert it to a CImg bitmap, scale it, add (in a higher resolution than
the original screenshot) annotations and write out a PNG file.

This is a reduced version of a bigger program, so it might be a bit more
complicated that needed just for the example.

U8g2: Library for monochrome displays, version 2

U8g2 is a monochrome graphics library for embedded devices. U8g2 supports controller based (for example SSD1306) monochrome OLEDs and LCDs (See the U8g2/U8x8 setup guide for a complete list of supported display controller). The Arduino library U8g2 can be installed from the library manager of the Arduino IDE. U8g2 also includes U8x8 library:

  • U8g2
    • Includes all graphics procedures (line/box/circle draw).
    • Supports many fonts. (Almost) no restriction on the font height.
    • Requires some memory in the microcontroller to render the display.
  • U8x8
    • Text output only (character) device.
    • Only fonts allowed with fixed size per character (8x8 pixel).
    • Writes directly to the display. No buffer in the microcontroller required.
