load Shader

for capturing errors

do the right thing for each type

save off old error stream

capture init errors

load the changed shader

return the default error stream

handle any errors

launch error, if there is one

be nice and mark where it happened

save off old error stream

capture init errors

launch error, if there is one

make the gl context current for loading might be dangerous
