get_font_default()

Get the default Font

load_font(file_name)

load_font_data(file_data, data_size, font_size, codepoints, type)

Load font data for further use

load_font_ex(file_name, font_size, codepoints)

Load font from file with extended parameters, use NULL for codepoints and 0 for codepointCount to load the default character set
