Can anyone explain how 8 bits ( one bytes ) are stored in a cairo's
surface under CAIRO_FORMAT_ARGB32 format?
For example, when I get data from a surface like:
unsigned char *data_cairo = cairo_image_surface_get_data (m_pSurface);
then, how to get A, R, G, B quantities inside *data_cairo?
# Baz said it is a endianness thingy but I don't fully understand it!
