When drilling from a chart to a category using the Drill to Category Chart Type, all the Category Object filters will be passed to the destination category in the same way that a normal drill down works.
...
If the ‘Filter’ box has been unticked for the Category Object filter on the source category, the Category Object filter on the destination category will not be changed when Drill to Category is used
If ‘Manually apply category filters’ is selected on the source category, the Category Object filter on the destination category will not be changed when Drill to Category is used
If the Dimension ‘Enable drill down filter’ is unticked on the source Category, the destination category will not be changed when Drill to Category is used
CatA Source chart Measures won't be passed to CatB - not sure on this one

Operators
Filters can have different operators, while each category object type only supports one operator.
So if If the filter (the source) is using an operator that the category object (targetdestination) accepts, the value is kept
Otherwise the filter is ignored
Current The following list shows the current supported Operators of each category object type, and the filter operators that can be used to set these category objects:
SELECT - EQUAL_TO - (accepts: EQUAL_TO)
SEARCH - IN - (accepts: IN, EQUAL_TO)
CHECKBOXES - IN - (accepts: IN, EQUAL_TO)
IMAGES - IN - (accepts: IN, EQUAL_TO)
NUM_PICKER - EQUAL_TO - (accepts: EQUAL_TO)
SLIDER - BETWEEN - (accepts: BETWEEN)
FREE_TEXT - LIKE - (accepts: LIKE, EQUAL_TO)
SINGLE_DATE_PICKER - EQUAL_TO - (accepts: EQUAL_TO)
DATE_PICKER - BETWEEN - (accepts: BETWEEN)
