/**
* @brief Draw partial source bitmap on LCD panel
*
* This function allows drawing a portion of a source bitmap to a specific area on the LCD panel.
*
* @param[in] panel LCD panel handle, which is created by other factory API like `esp_lcd_new_panel_st7789()`
* @param[in] x_start Start pixel index in the target frame buffer, on x-axis (x_start is included)
* @param[in] y_start Start pixel index in the target frame buffer, on y-axis (y_start is included)
* @param[in] x_end End pixel index in the target frame buffer, on x-axis (x_end is not included)
* @param[in] y_end End pixel index in the target frame buffer, on y-axis (y_end is not included)
* @param[in] color_data Source bitmap data
* @param[in] src_x_size Size of the source bitmap in the x-axis
* @param[in] src_y_size Size of the source bitmap in the y-axis
* @param[in] src_x_start Start pixel index in the source bitmap, on x-axis (src_x_start is included)
* @param[in] src_y_start Start pixel index in the source bitmap, on y-axis (src_y_start is included)
* @param[in] src_x_end End pixel index in the source bitmap, on x-axis (src_x_end is not included)
* @param[in] src_y_end End pixel index in the source bitmap, on y-axis (src_y_end is not included)
* @return
* - ESP_OK on success
* - ESP_ERR_INVALID_ARG if parameters are invalid
* - ESP_ERR_NOT_SUPPORTED if this function is not supported by the panel
