WCPS - keep the grid origin of left-handside operand in crsTransform()

[Bang Pham Huu]

e.g. this WCPS query:

for c in (test_mean_summer_airtemp)
return encode(
clip(

crsTransform(
c[Lat(-40:-30), Lon(120:130)] + c[Lat(-20:-10), Lon(140:150)]
, "EPSG:4326")

,

POLYGON((-40 120, -35 125, -30 130)) ), "png")

Petascope generates a rasql query with POLYGON starting with 0 18 for Long Lat axes, but it should keep the grid origin 17 43 from the first operand inside the project().

 SELECT encode(
clip( project( c[17:36,43:62] + c[57:76,3:22], "120.475,-40.474999999999987,130.475,-30.474999999999987", "EPSG:4326", "EPSG:4326", near ), 

POLYGON((0 18,9 9,18 0))
