Renamed to README.okular by: Tobias Koenig @ okular project 2006

>> Anti-Grain Geometry 2.3
The files contained in this directory are from the Anti-Grain Geometry library,
that provides many loosely copuled algorithms and classes for performing fine
rendering. All files in there are using a good bsd-like licence compatible with
okular development.
No external dependancies required other than a standard C++ compiler suite.

>> File Naming
- "agg_" prefixed files are from the Anti-Grain Geometry distribution. Those
  files are updated to the 2.3 release of that library
- "okular_" prefixed files are made by okular developers to extend library
  capabilities and fit the needs of that project.
- README.okular must be updated to reflect changes happening in that directory.

>> Directory contents
As AGG is a template based collection of tools, there is no need for the full
library, we need only a small subset of it. In fact in that directory there
are mixed Headers (.h) and Implementations (.cpp) files taken respectively
from:
  .h:   agg23/include
  .cpp: agg23/src
Note that directories "agg23/src/platform" (crossplatform GUI support),
"agg23/src/ctrl" (GUI widgets), "agg23/gpc" (generic polygon clipper),
"agg23/svg" (SVG viewer tool) are NOT USED AT ALL in the okular project.
