Improve blur items sizing
MultiEffect uses max 5 blur items. So to be able to divide first one 4
times without rounding, first one needs to be rounded up to next
2^4 = 16 (16,8,4,2,1). Make the first blurred item size half of the
source size (plus the rounding). This increases the blur amount and
performance and decreases texture memory usage and quality. Based on
testing it seemes like a good compromize.
Also resize bluritems only when needed.
