Possibility to clearing separate color and depth buffers

[amakaseev]

This function required in case when autoclean canvas is disabled for optimisation reason, and I need to draw 3d model on top of 2d. I need to clean only depth buffer before 3d draw. Also it would be useful if you do not use depth buffer, and you do not have to clear it.

@amakaseev did you mean to revert?

[ivanpopelyshev]

@bigtimebuddy I told @amakaseev in PixiJS slack that API changes are difficult to merge. He's working on better version :)

[bigtimebuddy]

Some small doc changes, thanks for the PR. If you could provide and example demonstrating usage, that would be very helpful as well.

[bigtimebuddy]

Thank you for those fixes.

Code-wise and backward compat, I’m good with this. I’ll let others comment on the utility/value of this feature.

@GoodBoyDigital how is it handled in your fork?

[GoodBoyDigital]

nice 👍

[bigtimebuddy]

@amakaseev could you resolve conflict with dev we just merged in a big PR to core. Hopefully the conflicts here should be minimal.

nvm, I got it!

Thanks for your contribution @amakaseev 🎉
