Not sure what you want. These functions return properties of the current font:
//------------------------------------------------------------------------------
uint8_t SSD1306Ascii::fontHeight() const {
return m_font ? m_magFactor*readFontByte(m_font + FONT_HEIGHT) : 0;
}
//------------------------------------------------------------------------------
uint8_t SSD1306Ascii::fontRows() const {
return m_font ? m_magFactor*((readFontByte(m_font + FONT_HEIGHT) + 7)/8) : 0;
}
//------------------------------------------------------------------------------
uint16_t SSD1306Ascii::fontSize() const {
return (readFontByte(m_font) << 8) | readFontByte(m_font + 1);
}
//------------------------------------------------------------------------------
uint8_t SSD1306Ascii::fontWidth() const {
return m_font ? m_magFactor*readFontByte(m_font + FONT_WIDTH) : 0;
}
setCursor(x, y) is pretty much the standard way to set the cursor in a graphics library. It allows you to position to the finest address on the display.

/**
* @return The current font pointer.

const uint8_t* font() const {return m_font;}

I think these functions are documented in the html here.
Click on SD1306Ascii.html. I will regenerate the html next time I update the library to make sure it matches the source.
