added: to Request:
// binary page
BinaryPage binary_page;
// a compressed page ready to send to the client
BinaryPage compressed_page;
// if true then either page or ajaxpage will be sent to the client
// if false then binary_page is sent
// default: true
bool use_text_page;
BinaryPage is defined as (in requesttypes.h):
typedef PT::TextStreamBase<char, 1, 4096> BinaryPage;
added: to Compress: now it can gets BinaryPage as arguments (input, output)
changed: winix version to: 0.5.0
added: in templates: TexTextStream class
for taking input to the TeX typesetting system
