Removed getTranslationX()/getTranslationY() calls during
invalidation.

Changed flag reading to use final constants.

Use int instead of long for duration millis comparison.

Use "switch" statement instead of consecutive "if"
statements.

Moved update time to updateDisplayListIfDirty() rather
than during invalidation in case invaliation happens
multiple times per draw.

Test: ran performance check. Now at 12% overhead
