PrimitiveCache::fitsBlock() function is always return true

[btrid]

PrimitiveCache::maxBlockBits variable is always constant 0xffffffffu.
These don't seem to make any sense, but are they implementation mistakes?

this is intentional, as different builder implementations exist. Just one is shipping with the sample, but in research I have different versions and they configure the PrimitiveCache class accordingly
