Tune PaperMono fastest-mode LUT parameters
Add M5ChainCaptain board support
quality / text render absolute 4-gray frames with dedicated waveforms. fast performs a three-step differential 4-gray transition based on the tracked displayed state, and fastest drives a single endpoint pass limited to the dirty rectangle. Mode 2 RAM face parity is managed explicitly, and BUSY is no longer sampled before it has asserted.
Implement four-mode refresh for SSD1677 4-gray panel
Add M5PaperDIY board detection and display support
Stabilize partial updates outside the dirty region, add calibrated Fast and Fastest differential waveforms, and make Text parity-aware. Use a single oscillating Quality activation for stronger ghost removal while preserving four gray levels.
Refine SSD1677 four-mode refresh waveforms
- pgmspace.h: make pgm_read_3byte_unaligned alignment-safe on platforms without pgm_read_dword_with_offset (lovyan03/LovyanGFX#865) - LGFX_Sprite.cpp: accept valid top-down BMP imports and reject INT32_MIN height (lovyan03/LovyanGFX#864) - pixelcopy.hpp: restore ARGB8888 destinations in get_fp_copy_rgb_affine (lovyan03/LovyanGFX#862) All three files are byte-identical with LovyanGFX develop after this change.
Sync fixes from LovyanGFX develop and bump version to 0.2.26
