Subject: Added ScaleFilters class implementation to the
X-Git-Tag: v0.0.90~384^2~202
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=5f203e6553fb38c26dd3296c423f5e0db123a4b7;p=tigervnc.git

Added ScaleFilters class implementation to the
ScaledPixelBuffer. It's routines to manipulates a set of
1-d scale filters.
