Bug 1081: Fix GLJPanel Regression: Honor pre-init reshape-size at initializeBackendImpl()

Commit 84f367a73c5b16dcebfd877e82e1c2cb90ae74ce removed utilization of reshape-size
in case panel-size is valid, even if a reshape event happened in between:
  - addNotify
  - paintComponent

initializeBackendImpl() includes now uses reshape-size IFF handleReshape is set.
Before it was using reshape-size only if panel-size was invalid.

TestAWT03GLJPanelRecreate01 covers this issue.
