+**LOAD_FULL_RES_IMAGE=YES/NO**
+    This option affects how image data is loaded for the resampler when
+    reprojecting or otherwise going through complex resampling (as opposed 
+    to the fast default image decimation code path).  This forces the source
+    image to be loaded at full resolution if turned on (default is NO).  This
+    helps work around problems with default image resolution selection in 
+    when radical warping is being done.  It can result in very slow processing
+    if the source image is large.
+
+**LOAD_WHOLE_IMAGE=YES/NO**
+   This option affects how image data is loaded for the resampler (as above).
+   This option, if turned on, will cause the whole source image to be loaded
+   and helps make up for problem identifying the area required, usually due
+   to radical image reprojection near a dateline or projection "horizon". 
+   The default is NO.  Turning this on can dramatically affect rendering 
+   performance and memory requirements.
