Fixed a couple of regressions from namespace refactoring
From the ES3 spec, section 4.4.2 (about DeleteRenderbuffers):
"Unused names in renderbuffers are silently ignored, as is
the value zero."
And from section 6.1.5:
"IsSampler will return TRUE if sampler is the name of a
sampler object previously returned from a call to
GenSamplers and FALSE otherwise".
Also, glIsSampler can use Context::isSampler(), which uses
ResourceManager::isSampler(), which should only look whether a
name has been reserved, not whether the object is allocated.
Note: Even though the spec mentions (about Sampler objects):
"they acquire state only when they are first used as a parameter
to BindSampler, SamplerParameter*, GetSamplerParameter*, or
IsSampler", it shouldn't hurt to not allocate the object when
calling IsSampler, since a subsequent call to any other Sampler
object related function should allocate it.
