glHistogram and ARB imaging
Last update on .
The docs for glHistogram clearly say that if the GL_ARB_imaging extension is not supported then glHistogram is not present... except it appears to be present (and even accepts calls), but if I pass GL_HISTOGRAM to glEnable( ) I get an invalid enumerant error.
I'm pretty sure this card *should* support the whole of the imaging extensions (it's an ATI Mobility Radeon HD 3650), but it does not declare itself to support ARB_imaging. So it seems that, while the *function* is there, its *functionality* is not there if the ARB_imaging extension isn't declared.
It is to sigh. Half an hour wasted on this, which means I'm not likely to get a new release out today.
