--BIG PERFORMANCE PB
-- try to revert to love 11.1
-- pb only with custom built love 11.3

-- init of save directory : might not create if folder exists in prj folder

--zaz2nim
---- parameterize project canvas size ( 640 480 , 1920 1080 ) in config file of project 
-- require of config works
-- insert perf logs
-- palette bug > only some colors can be picked

-- screen scalling incorrectonandroid
--simpletouchwithout dragdoesn'twork dotimpossible
-- DONE flickmode
-- TODO script to migrate zazanim project
--TODO time code screen
-- TODO copy range
-- TODO zoom mode
-- TODO queue fill mode
-- TODO shader fill mode
-- TODO bg layer
-- TODO virtual camera


-- minimum for mobile:
-- WIP settings screen with brush size
-- auto folder creation for project on android
-- toggle display of eraser button
--  scroll save TODO palette buttons
-- WORKS copy frame
-- test on android sd ( all devices )
-- NOTE 3 neo slow in hd
-- note 8 ok
-- note 4 untested
-- gtn 5110 untested
-- lenovo a310 untested
-- NOTE 8 NOK GTN5110 NOK
-- 		frames are destroyed when scrolling
-- 		cvs save works in unit test on android
--		try disabling display when downloading tex 
--		try saving files when downloading
-- draw zazahead slowly then change feature = load splash
-- WIP pic button zith spritesheet


-- TODO do not use load filter for project load,
-- having drawable is not useful ( and must take up memory )
-- TODO do we need to release tex allocated all the time ?
-- brush

-- TO DECIDE ui cvs has same size and zoom as project canvas
-- BUG the brush is blit top left, not centered
-- DONE round brush 
-- DONE line interpolation
-- BUG add frame only adds at end of project, insertion should be possible
-- WIP smooth ink shader
-- 		chosen ink color should be alphaed on neighboring pixels ( fireman ben style )
-- 		TODO the notion of canvas is not the same in zaz2nim
--		probably the canvas should be reblitted on a canvas of the same size, then scaled up?
--		otherwise the result will look different than target res?
-- try unit test in subfolder of project with main.lua
-- TODO interpolate unit test
-- TODO performance logs
-- DONE save modified buf even if no scroll
-- TODO save with smooth shader
-- TODO virtual scroll (scene larger than screen)
-- TODO file requester


-- TODO sound capture test
--https://love2d.org/forums/viewtopic.php?t=86173


--TODO drag and drop widget for cut and paste
-- based on mtdt titler boxes
--poc paint to canvs 
-- poc save to file and scroll with ul and dl of image data
--TASKS 
-- add pic button
-- note 3 neo test
-- note 8 tab test
-- perf logs on ul dl of tex
-- make resolution a variable
-- instead of blitting alpha brush (which modifies color because blends with bg even at alpha 0)
--   use canvas to store what is done on the canvas (keep brush color with some alpha)
