Multiple undos

[unitycoder]

Currently only 1 undo step is possible, because all drawing is applied to the texture directly. More undo steps would require saving multiple copies of the whole texture (or atleast parts of it)

i tested it on :

• iphone 5 ios 8.4.1 it works great with 60 fps
• ipad air 2 ios 8.4.1 it works great with 60 fps
• samsung nexus s Android 4.1.1 (worst case scenario) laggy
• samsung tab A android 5.0.1 laggy but somehow acceptable

note : for android i'm not so sure it is lagging cuz of undo or some stuff need to be optimized in my code

On androids it does get slow if you use full screen resolution, like 2048×1536, that is huge texture to update.. (using resolution scaler like 0.5 or 0.25 helps alot, then can add post effect to camera for extra antialias to smoothen it)

i'm looking into adding option to split canvas to smaller pieces which should fix it, but makes flood fills, patterns paints etc. bit difficult to handle..

one thing I'm trying to make the user get list of the colors he used to color his room walls i can just record the selected colors but if the user erased the color then it should not be in the list do u have i a way to do it without effect the performance and read the pixels colors again.
