Tangent brush compared to a Normal map RGBA brush tip

SUMMARY
RGBA brush tips only work properly in 8bit if they were created in a 8bit document.

STEPS TO REPRODUCE
1. make a RGBA brush with a 8 bit image
2. make a new document and use your new brush
3. your brush if it is not in 8bit will be with inverted colors

OBSERVED RESULT
my brush has inverted colors unless I make a 8bit document

EXPECTED RESULT
my brush to paint with the correct colors I set on it.

SOFTWARE/OS VERSIONS
Windows: 10
Qt Version: 5.12

that's because color management happens on the RGBA brushtip. This is intentional, until we implement 16bit color brushtips.
