[Follow up] Improve performance when rendering sample waveforms
This PR adds additional changes on top of #7366:
- Attempts to resolve the garbage rendering issue when viewing large samples.
Details
In the old code, `m_paintPixmap` in `SampleClipView` is allocated to the size of the whole clip, and painted at (0, 0) no matter what. On large samples, when the width exceeds 32768 (QPixmap's resolution limit), garbage data will be shown.In this PR, m_paintPixmap is allocated to the paintEvent's size (but with the clip's height), and painted onto the clip at the paintEvent's X coordinate. To make sure the m_paintPixmap doesn't get drawn on the wrong coordinate (due to something overlaying the clip and changing the paintEvent region), we paint on the coordinate obtained from the last full redraw.
This change allows some fields of VisualizeParameters to be omitted (drawRect).

Fixes lagging in Automation Editor by specifying the viewportRect.
-
Fixes crashes:
-
Simplifies and enhances the implementation.
Should resolve the sample clips part of #3378
