Can't rotate display

[buteomont]

I chose this library because of its small footprint and simple interfaces. Everything in my project works great except I need to be able to rotate the display 180 degrees. I believe the SSD1306 chip has the hardware capability for this, but I don't know how to do it. I imagine it would be a simple addition to the otherwise excellent library for someone that knows how to do it.

Ok, I actually figured out how to do this. In oled.cpp lines 248 and 249 I changed
i2c_send(0xA1); // segment remapping mode
i2c_send(0xC8); // COM output scan direction
to
i2c_send(0xA0); // segment remapping mode
i2c_send(0xC0); // COM output scan direction

Perhaps overloading function begin() with begin(boolean rotate180)?
