REPORT-55491 【交互验收】【组件背景分离】在组件属性下的「主体背景」设置,在配置界面不生效,看不到效果

【问题原因】
1. 绘制报表块缩略图时,填充了白色背景,导致组件样式背景被覆盖
2. 优化报表块缩略图时,即在ElementCaseImage中截取部分缩略图时,丢弃了Alpha通道
3. 表单布局预览绘制表格缩略图时使用了默认的白色纸张背景(表单报表块的表格没有纸张背景的概念)
【改动思路】
1. 绘制报表块缩略图时,不要使用白色背景填充,保持透明
2. 优化报表块缩略图时,使用subImage完成截取功能,保留Alpha通道
3. 表单布局预览绘制表格缩略图时,忽略纸张背景
4. 替换默认的报表块预览图(此图用于将报表块拖拽到面板中时显示作为
报表块的缩略图使用),因此也要支持半透明
