Author : raster
Project : e17
Module : libs/evas
Dir : e17/libs/evas/src/modules/loaders/svg
Modified Files:
evas_image_load_svg.c
Log Message:
added the ability to set load scaledown, dpi or load size - the svg loader
uses these to know what to render and how (or has defaults if these are not
set)
