Huge performance hit for iOS and Android (at least for version 2.8.8)

[kodyrouse]

Just wanted to let you guys know there is a massive dip in performance on mobile in version 2.8.8 compared to 2.6.2 (using apache cordova) with no changes to my code. There seems to be no noticeable difference on desktop. I assume it's a rendering issue but I'm not entirely sure. I reran it on a Samsung Galaxy S6 and was debugging in Chrome and noticed this was being logged:

I double checked back with version 2.6.2 and nothing was logged

**** Edit ****

I just did some testing with Firefox Canvas debugging and took some snaps of the exact game scene. Results below are both for desktop.

Phaser 2.6.2

Phaser CE 2.8.8

See #194, #198, #335.

#194 Helped with the first issue - well, it at least makes to stop logging an issue!

#198 Is related, but there doesn't seem to be a solution yet :/ I'm still going to try to figure out what's causing the issue. It would be wonderful to take advantage of the multi-texture support in the CE version.
