Ben Clayton 0a3cda9911 tint: Replace all ProgramBuilder float literals with '_f' suffix 
Unsuffixed float literals are currently treated as f32,
but will shortly become AbstractFloat. To keep tests behaving
identically to how they are currently, change all float literals
to explicitly use the f32 '_f' suffix.
