+
+ Syntax: ``RESQ dst, resource``
+
+ Example: ``RESQ TEMP[0], BUFFER[0]``
+
+ Returns information about the buffer or image resource. For buffer
+ resources, the size (in bytes) is returned in the x component. For
+ image resources, .xyz will contain the width/height/layers of the
+ image, while .w will contain the number of samples for multi-sampled
