new tool for drawing pixels  (inspired by `Tomato` 's new avatar)

I recommend using size 20 you get nice a resolution of 30x25 pixels that way but other sizes work too and 5 is the smallest that works ok


:o I am working on a 16bit side scroller game, now I can practice pixel art, awesome new tools `Peyo` , you spoil us my friend!

`Painovoima` this one was one of those easy to implement features actually.. I just didn't know there was a demand 🙃

You are a legend Peyo, can’t wait to see how others use it 😁👌

would it be possible to make it so it shows a grid when youve got the pixel tool selected, correlating to the brush size you have? also i went ahead and made a new icon for it cause honestly the current icon is not obvious as to what it actually is 

`Carrot^abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqr new line` sure! for now I added it to my (local) todo list.. hmm.. maybe toggling the grid should use a seperate button? (I guess we could reuse the old icon for that)

oh yeah, the grid being optional is a good call id say maybe have it as an option under the gear menu for the time being? or have it show up somewhere only while the pixel tool is active, kinda how the onion slider appears only when you have onion skin on once you implement the contextual window, you can have the grid toggle in there

Peyo when people come to your site go... "LET ME SHOW YOU ITS FEATURES" https://youtu.be/vdjGIpqb32g?t=22

wat （⊙_⊙） I would hate to work in an office with that guy 🤔

`Carrot^abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqr new line` ok here you go see if you like it once again my lazyness inspired me: just click it again to enable or disable the grid (its disabled by default because it was slow on the local version - but here on the live one it seems quite fast - I don't get it)

looks good, great work `Peyo`
