closes #3505
There where errors and optimization possibilities:
after a mouse up the text was redrawn, using a cachied copied. the code for drawing the selection was inside the cache creation, and so it was not executed during the faster drawing. this was the main error.
after mouse up there was no need to re render, this is an optimization
during keypresses of arrows where just the cursor selection changes, there is no need for a full canvas redraw. this is an optimization
