41 Description:
42 Draws normal or inverted text with optional frame around text.
43 The text (and the frame) can be horizontally centered around the provided reference position.
44 This procedure will use the current draw color and current font. The height of the frame
45 depends on the setting of setFontRefHeightText(), setFontRefHeightExtendedText() or setFontRefHeightAll()
46
47
48 Note 1: drawColor 2 (XOR) is not supported. Result will be broken with draw color 2.
49 Note 2: This procedure will enforce font mode 1 (transparent mode)
50 Note 3: Some fonts may add an extra gap on the right side. This is a font problem and can not be avoided (for example inb16 has this problem).
51
52
53 The height of the button is defined by the current font and
54 setFontRefHeightText,
55 setFontRefHeightExtendedText
56 setFontRefHeightAll
57 Right padding might be influenced by the font.
58 For example u8g2_font_inb16 may add an extra pixel gap (increase padding by one)
59 on the right side.
60 The current draw color is considered, but only draw color 0 and 1 are supported
61
62 This function requires transparent font mode: setFontMode(1)
63
64 Side effect: Font transparent mode is enabled setFontMode(1)
