There was a fixed limit to the number of points available in a buffer stroke. Now, the array is expanded as needed using a predefined number of points for each expansion, instead to add one by one. This is done to reduce the number of times the memory allocation is required. As part of the fix, some variables have been renamed to reflect better their use.
