# The "convert" program from imagemagick can be used to create png from svg but doesn't properly deal

# Graphical layout of icons and our portfolio
# ===========================================
#
# We have two different kinds of icons in our artwork collection
#
#   a) The mimetype icons have a different graphical layout depending on resolution
#      This assumes that a higher resolution means a bigger size. On the bigger
#      size you can identify more details and this is used in the design.
#   b) Icons which are designed based on 16x16 pixels which are just scaled
#      This are all other icons.
#
# Icon resolutions
#
# The different icon resolutions are historically derived for bitmaps when an icon
# is displayed in different sizes. Then a scaled version of the icon requires a new
# bitmap image. All our icons are now svg type and can be scaled from one svg file as
# the names suggests - scalable vector format.
#
# The strategy for pspp gui
#
# All icons which are simply scaled provide a default 48x48 bitmap png image plus
# an svg version in the scalable directory.
# The mimetype icons with different layouts provide png bitmaps in their original resolutions
#
# The artwork directory contains only the pure source svg files. No copies and no
# version has another size indication although it is an svg.
#
#  => mimetype icons are located in 16x16, 32x32, ... , 256x256 (different designs)
#  => all others are in scaled (just one design svg)
#
