Right! Good thinking!

gegl/gegl.spec:BuildRequires:  pkgconfig(jasper) >= 1.900.1
gegl-unstable/gegl-unstable.spec:BuildRequires:  pkgconfig(jasper) >= 1.900.1
OpenSceneGraph34/OpenSceneGraph34.spec:BuildRequires:  pkgconfig(jasper)
OpenSceneGraph/OpenSceneGraph.spec:BuildRequires:  pkgconfig(jasper)

Also:
telegram-desktop/telegram-desktop.spec:Requires:       jasper

I'll create SRs or bugs for them.
