Use OfFloat Point values to create precise highlight brackets

[ShahzaibIbrahim]

Because of rounding errors the bracket selection highlight is often inconsistent. Making use of residual values provides precise rectangle values and highlight is consistent across all zooms

How to test

• Run the runtime workspace with monitor-specific scaling turned on
• Add some brackets in Java file { }
• Select the opening bracket, the closing bracket will be highlighted.
• See if the rectangle around highlighted bracket is surrounded the bracket correctly (no-cutoffs)
