The Feb newsletter mentions the addition of these new commands to the new 107 release.

SetScissor()
SetSpriteSnap()
SetSortCreated()
GetPixelsDrawn()

What do these do?

Good question! I was wondering about those too...

I'm guessing:
SetScissor() - crop a sprite?
SetSpriteSnap() - make a sprite snap to a position based on a value IE. Rounding sprite positions?
SetSortCreated() - array sorting?
GetPixelsDrawn() - get the number of pixels that have a sprite / text pixel drawn on the back buffer (IE. not background colour)?

Just guessing though...

As have I.

I think it's more GET IMAGE oriented but I'm only guessing as well.

I'm very curious about the GetScissor() command.

I wish I could help you out there but sadly I can't

Hopefully the rest of the drawing commands will be in there and it would be nice to have access to device cameras where available. Whatever is there will be very useful and a fun new addition I'm sure!

I am much more keen in the network commands... and it seems I will be restricted to just the android market unless google decides to charge a yearly fee too...

I'm quite looking forward to the http commands and the AdMob stuff; the Date and Time commands are a godsend as well. I was also quite looking forwards to the image creation commands for my UI Module, but I have spent the last two weeks working out ways to code it without them.

@MrValentine:
Is the $25 licence fee for Android development a one off payment then? I just assumed it was yearly the same as the iOS one is.

Dunno regardless $25 compared to $99 is breathable... I think the Android one was one off but I can not see that link of yours without singing in and sorry but I do not want to do it at the moment... what does that page state?

I'd not actually checked into it this much before (I was leaving it till I had a game finished, lol). I had read that an Android licence was about £30 a year; but the sign up page makes me think it's a one off.

(hate it when UK costs are higher than US costs)

[ie... in USD$ its $50 and in the UK GBP its £50 ]

SetScissor() - Sets up a rectangle that will clip all rendering, can also be set per sprite to clip individual sprites.
SetSpriteSnap() - Turns on/off the coordinate rounding that forces sprites onto whole pixels to stop some flickering when sprites move across the screen. But when turned on it can look like the sprite is jumping from one pixel to the next, so it's optional.
SetSortCreated() - draw sprites that have the same depth in the order they were created (the documentation saying this already happens was in fact optimistic and not correct in all cases), it's slightly more work for the renderer to do, so it's optional.
GetPixelsDrawn() - Returns a rough estimate of how many pixels were drawn in the last frame, good for checking fill rate limited devices.

Ah, very interesting. Thanks Paul!

Is co-ordinate rounding turned on or off by default when using a pixel based system (IE.setVirtualResolution)?

In the current version it attempts to detect when coordinate rounding should be turned on, mostly if a sprite is non-rotated, but the new version will keep it on or off based on your preference. The coordinate system has no effect on it as you could still position a sprite at an X value of 10.5 even on a one to one pixel resolution.

If I read SetScissor right, I sure wish I would have had that for Double Pinochle. Oh well, I'm sure these and all of their other commands will be handy for someone.
