Functions
void	gfx_clear (gfx_color_t color)
	Fill the whole framebuffer with one color.
void	gfx_pixel (int x, int y, gfx_color_t color)
	Set one pixel; off-canvas coordinates are ignored.
void	gfx_fill_rect (int x, int y, int w, int h, gfx_color_t color)
	Fill a rectangle, clipped to the canvas.
void	gfx_draw_rect (int x, int y, int w, int h, gfx_color_t color)
	Draw a 1px rectangle outline.
void	gfx_draw_text (int x, int y, const char *s, gfx_color_t color, int scale)
	Draw an ASCII string (0x20..0x7E) left to right.
void	gfx_blit_1bpp (int x, int y, int w, int h, const uint8_t *bitmap, gfx_color_t color)
	Draw a 1-bpp bitmap; set bits are drawn in color, clear bits are skipped.
void	gfx_flush (void)
	Blit the framebuffer to the OLED over SPI.
const gfx_color_t *	gfx_buffer (void)
	Read-only access to the framebuffer (GFX_W*GFX_H pixels).
