###CURRENT: ###TODO:

Packaging: freenode:#opensuse-buildservice:darix osc linkpac openSUSE:Factory/libircclient AvCaster: GetIsEnabled() functions and possibly IsEnabled vars are probably not needed - perhaps their semantic could be to set *_ACTIVE_ID storage false and disable the control buttons AvCasterStore: eliminate FIX_OUTPUT_RESOLUTION_TO_LARGEST_INPUT IrcClient: bitlbee login fails if another client already logged in how to detect other mods in lctv chat implemenet chatlist kick button Gstreamer: Gstreamer: eliminate NATIVE_CAMERA_RESOLUTION_ONLY eliminate AvCaster::GetVolatileStore(), Gstreamer::ReloadConfig(), AvCaster::GetIsPreviewActive() by passing Store->config into Config, Controls, Gstreamer implement text implement interstitial replace testvideos with alpha img or fakesrc

verify the runtime dependencies
connect remaining config GUI controls
sanity checks/validations
test for device/screen existence
detect camera resolutions and implement device storage (moving CAMERA_RES_ID out of main store)
GUI styling
GUI tooltips
translations
scale inputs to fill compositor output

TODO: after JUCE upgrade

change listeners of old form SliderListener to new form Slider::Listener
add back codeblocks projects $(if $(filter-out x86_64 , $(shell uname -m)) , -malign-double , -fPIC) (after upgrade) $ CONFIG=Release32 PKG_CONFIG_PATH=/usr/lib/i386-linux-gnu/pkgconfig/ make
