/*
* \@file evas_filter.c
*
* Infrastructure for simple filters applied to RGBA and Alpha buffers.
* Originally used by font effects.
*
* Filters include:
* - Blur (Gaussian, Box, Motion) and Shadows
* - Bump maps (light effects)
* - Displacement maps
* - Color curves
* - Blending and masking
*
* The reference documentation can be found in evas_filter_parser.c
