The currently included version of libfreetype already has the LCD subpixel filter turned on by default. With the switch from my "averaging filter" back to Adrej Spielmann's filtering, there was now another filtering being done on top of what Freetype already does. There also seemed to be a problem with the left edge of cached glyph bitmaps, which I didn't bother to look into. The visual result of this change is that text looks much crisper, and the display bugs at touching glyphs is gone. On the other hand, LCD sub-pixel rendering is still turned on globally, i.e. for all vector drawing, and for uncached rotated text. The Freetype filtering is not applied there. This problem did not exist in my "average filter", since it happened at the scanline rendering level, not only for cached glyph bitmaps. It is however not a regression introduced by this commit. It needs to be fixed separately.

Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
