bindTransformFeedbackInfo with offset

https://github.com/greggman/twgl.js/blob/e685cf96ecb171839810dca5480834abe8c86919/src/programs.js#LL1149C20-L1149C20
The function bindTransformFeedbackInfo accesses the "size" of an attribute of the bufferInfo, however, "size" is an alias of "numComponents", which means that when you try to configure "size" you end up configuring "numComponents".
