This interface could be simpler. The unpacking from the data to the
internal format should take place in mesa/main, so that drivers only
have to implement something like this:
void (*ClearBufferSubData)(struct gl_context *ctx, struct
gl_buffer_object *obj, GLintptr offset, GLsizeiptr size, GLvoid
*element, int element_size);
"offset" and "size" should stay. "element" is the clear value that has
"element_size" bytes. "element_size" is the size of the internal
format in bytes.
Marek
That's something I considered, but I thought the drivers might have
their own way of converting the data to the internalformat.
If that's not the case, I'll change it.
I like Marek's idea too. Can you please try that?
