News/release from Gonetz:

This is a realtime texture enhancer library with hi-resolution texture pack support for Glide64 http://glide64.emuxhaven.net . Traditional and non-traditional techniques have been used to achieve speed and high image quality even on a 9 year old 3Dfx Voodoo2.

Version 9
New set of fixes by KoolSmoky
Glitch64: fixed status bar issue with 1964 in full screen mode
GlideHQ: More muli-core utilization with GlideHQ. The x2Sai, Smooth, etc enhancers and filters, color quantizers have been modified, so realtime texture enhancements and filters are faster on a multi-core CPU.
