snippet: Fix detecting the last snippet

Browse Source 
The function for generating the GLSL for a list of snippets was trying
to detect the last snippet so that it could use a different function
name. However this wouldn't work if the last snippet has a different
hook. To fix this it now just counts the snippets that have the same
hook beforehand and detects the last one using the count.
