* switch-cases that fall through
* potential buffer overflow in improv.cpp
* potentially uninitialized variables in FX.cpp
* potential array out-of-range on segment::col[]
* minor optimization: only apply gamma correction when result is needed
* tag some possibly unused variables with [[maybe_unused]]
Introduces new memory allocation functions, based on wled#4895 by @DedeHai
* keep a minimum of 15KB RAM available to UI - improves stability
* S3/S2/C3 automatically use "fast RTC Ram" for small data (reduces fragmentation)
* auto-detects PSRAM (or no PSRAM) when firmware was built with -D BOARD_HAS_PSRAM
* d_malloc() and d_calloc() prefer DRAM if possible (faster), but fall back to PSRAM when free RAM gets low.
* added missing check for "ledmap.json" file => always applied
* added missing check for ledmap1...10
* setupMatrix test for "unity" ledmap was too early - removed (need to find a better place for this)
* replace strlen with strnlen
* avoid static variable in getFontInfo
* remove legacy code in drawCharacter (new code works well)
it works for me, let's ship it ;-)
* centralize font selection logic into getFontInfo()
* removed unneeded parameter "numberOfChars" from drawText()
* new file: wled_fonts.hpp to centralize font management logic (inline)
* only compile wchar16ToCodepage437 when WLED_ENABLE_FULL_FONTS
* minor cleanup
* explanation for CP437 glyph groups
* translation for MonnModules symbol
* "smiley" replacement for 4-bytes and overlong unicode codes
* always compile unicodetool.cpp (codepage translation still depends on WLED_ENABLE_UNICODE)
* bugfix: DrawString now skips over glyphs that would be rejected by DrawCharacter
* minor cleanup
* introducing WLED_MAX_SEGNAME_LEN from upstream
* default: max name length = 48
* hopefully found all places where the segment name length was hardcoded (32, 33, 34)
* some comments still refer to "32" but wtf
* make sure that filenames can hold 32chars of segment.name
* fix logic error in Segment::drawCharacter
* protect free(Segment::_globalLeds) with a critical section
prevent errors / crashes when drawing "i" images from a preset.
- prevent out-of-bounds writing (segment smaller than image)
- make sure that segment properties are cached correctly
- always do "show" when strip was triggered (avoids lost frames)
* moved sPC and gPC functions out of their .cpp files into FX.h, so the compiler can optimize better.
depending of effect used, this gives a 2% up to 8% speedup.
* make XY() and _setPixelColorXY_raw() const (minor speedup)
* segment is a struct not a class: friend class Segment --> friend struct Segment
* fix missing braces around two macros
* use non-throwing "new" where possible
* improve robustness of transition code
allows the compiler to inline access to ledsrgb[] , while still keeping the "no buffer" case in a separate function so program size does not blow up.
--> up to 10% faster
some usermod still seems to used sPC(float, float, c).

.pio/build/esp32_4MB_XL/src/usermods_list.cpp.o:(.literal._ZN7Frame3DD5Ev[Frame3D::~Frame3D()]+0x4): undefined reference to `Segment::setPixelColorXY(float, float, unsigned int, bool, bool)'
similar to getPixelColor, but returns the original pixel without brightness adjustments.
* getPixelColorRestored is used by segment::sPC and segment::gPC
* getPixelColor is still used by ABL (auto brightness limiter)
the problem (partly solved) is that scrolling text does not erase any previous text, but simply paints pixels in addition.
* add a "shadow" area around each letter, which is explicitly painted black
* only possible when Trail=0, and overlay option selected
