* \brief Draws an aligned string located in program memory to the display

* This function will draw a string located in program memory to the display
* with the specified alignment. This differs from gfx_draw_aligned_string() by
* using constant string data from the program memory instead of string data in
* RAM.
*
* \param str Pointer to string located in program memory
* \param x X coordinate on screen.
* \param y Y coordinate on screen.
* \param font Font to draw string in
* \param bg_color Background color to draw behind the text string
* \param text_color Foreground color to draw the text string in
* \param text_pos Position of the coordinate relative to the text paragraph
* \param text_align Alignment of text lines within the paragraph bounding box
