Added self.font_profile, glyphs and profile fallback character as new parameters of the DisplayBase class to wire up the added display_font config section. Signed-off-by: Christian Hofbauer <chof@gmx.at>
Added the following classes following the strategy pattern to customize font source loading, swizzling and font cache building: - FontSourceStrategy: Loads the font and return font parameters - SwizzleStrategy: Convert from "rows of pixels" format to display native format - FontCacheBuilder: Combines the sourcing with swizzling to load a font ready for the display Signed-off-by: Christian.Hofbauer <chof@gmx.at>
…EDs with klippy - introduce font rading and swizzling strategies - add `BuiltinVGAFontSource` and `PageSwizzleStrategy` to provide builtin and external font loading - refactor `uc1701.DisplayBase` to use swizzled `FontObject` rendering (dynamic glyph width/pages) instead of hardcoded VGA tuples - add SSD1306 panel `height` support (`32|64`) and select mux/COM init commands from configured panel height to allow customizable line heights - move `DisplayFont` config parsing into `klippy/extras/display/fonts` and wire `[display] font` to OLED chips in `display.py` - rename and integrate BDF loader as `BdfFontSource` with strategy registration in `DISPLAY_FONT_SourcingStrategies` Signed-off-by: Christian.Hofbauer <chof@gmx.at>

Intent
Extends the build-in VGA fonts with configurable text fonts for OLED displays. To enable larger/custom fonts on SSD1306/SH1106 displays.
High-Level Solution
Introduce a pluggable font pipeline in Klipper display code.
A new
[display_font <name>]section defines external font profiles (currentlybdf), and[display]can select one viafont: <name>. OLED rendering is updated to use dynamic font metrics and panel height (32/64) instead of fixed assumptions.High-Level Changes
