            Description

            We have many clients that use the library to read very complex architectural diagrams. These PDF's can have missions of shapes and often slow to parse and paint. The bug will capture some of the issue and potential optimizations.

Also found an issue where we would block the awt thread to paint selected text even if there wasn't any.

              Several updates around improving performance on" heavy" shapes PDF docuemnts.

              • limit the number of times we set the alpha draw cmd
              • limit where we can the number of clips we set.
              • clip calculation now use bounds instead of bounds2d where possible.
              • fixe dan awt thread blockign issue which slowed down the initial paint of page.
              • fixed an issue where decode was being applied more then needed.
