* \@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
