[TIMOB-24898] Allow background transparency when borderRadius is set

[garymathews]

• Disable canvas hardware-acceleration when a view has a border and background transparency set

TEST CASE

• Label should be visible before and after clicking the view

var win = Ti.UI.createWindow({title: 'TIMOB-24898', backgroundColor: 'gray'}),
    view = Ti.UI.createView({
        width: 300, height: 300,
        backgroundColor: '#00202020',
        borderRadius: 6, borderWidth: 2,
        borderColor: 'red'
    }),
    lbl = Ti.UI.createLabel({text: 'VISIBLE', color: 'white'});

view.addEventListener('click', function() {
    if (view.backgroundColor.startsWith('#00')) {
        view.backgroundColor = '#AA202020';
    } else {
        view.backgroundColor = '#00202020';
    }
});

win.add(lbl);
win.add(view);
win.open();

Question:
If a border radius triggers this issue, then why does the following not fix this issue?

@jquick-axway Yes it would, but not in the case of Jellybean and higher. There's so many edge cases for HW acceleration..

I could increase the bounds of that condition, but I want to keep HW acceleration enabled for the most cases without causing issues.

CR: Pass

1. Checked it with different values of borderRadius
