+ * @brief Apply behaviour of tags if the markup-processor is enabled.
+ *
+ * The properties on TextLabel override the behavior of Markup.
+ * Because the markup will be the bottom layer buffer
+ * - i.e: If you set property UNDERLINE to enabled and blue.
+ * And the TEXT is "<color value='green'>Hello</color> <u>World</u> <i>Hello</i> <b>World</b>".
+ * Then the output of the whole text is underlined by blue line.
+ *
+ * @param[in] topPixelBuffer The top layer buffer.
+ * @param[in] bufferWidth The width of the image buffer.
+ * @param[in] bufferHeight The height of the image buffer.
+ * @param[in] ignoreHorizontalAlignment Whether to ignore the horizontal alignment, not ignored by default.
+ * @param[in] pixelFormat The format of the pixel in the image that the text is rendered as (i.e. either Pixel::BGRA8888 or Pixel::L8).
+ * @param[in] horizontalOffset The horizontal offset to be added to the glyph's position.
+ * @param[in] verticalOffset The vertical offset to be added to the glyph's position.
+ *
+ * @return The image buffer with the markup.
