Detailed Description

Adafruit_GFX-compatible facade over lcdgfx displays.

Drop-in Adafruit_GFX-style API implemented on top of any lcdgfx display or canvas, requiring NO external Adafruit_GFX library.

Existing sketches written against the ubiquitous Adafruit_GFX API (drawPixel/drawLine/fillRect/print/setCursor/... with int16_t coordinates and a trailing uint16_t color) can run on any display supported by lcdgfx by wrapping the display in a GfxCompat adapter:

DisplaySSD1306_128x64_I2C display(-1);
GfxCompat<decltype(display)> gfx(display);   // or: auto gfx = makeGfxCompat(display);
void setup() {
    display.begin();
    gfx.fillScreen(0);
    gfx.drawRect(0, 0, 128, 64, 1);
    gfx.setCursor(10, 10);
    gfx.print("Hello GFX");
}

The adapter is a zero-overhead, header-only template: it forwards directly to the underlying lcdgfx primitives (no virtual calls, no buffer). color is passed through unchanged, so it carries the same meaning as for the underlying display (0/1 for monochrome, RGB_COLOR8/RGB_COLOR16 for color panels), exactly like Adafruit_GFX.

Note: Intentional differences from Adafruit_GFX: text scaling (setTextSize) is honored only at size 1 (lcdgfx uses fixed-cell fonts); setRotation is stored but rotation is controlled through the underlying display's own configuration. These are stubbed so GFX sketches compile unchanged.
