Fix T47147: small particles incorrectly rendered as large particles (particle size influenced by texture).

In fact, code would behave strangely here with any negative value, applying a 'wrapped positive clamping'
(comes from original 2.5 commit feature, rBfafbd9d71b95776d1c7583476de74fccefab7f10)...

This commit is conservative - it keeps same behavior for all particle properties affected by textures,
except for size and length, where we apply a real [0, 1] clamping.

Easy to change in future in case new odd cases popup.
