The graphs on the Task Manager "Performance" tab did not update their size correctly when the window was being resized. This resulted to the graphs being clipped to the default (small) size. This patch releases the existing memory DC and bitmaps when the control is resized and allocates new ones. It also switches from having only 4 horizontal grid lines to having a grid line every 10 rows, making for a grid of squares rather than vertically stretched rectangles.
