* Removed CMATH

Co-Authored-By: Rodrigo Faselli <162915171+RF47@users.noreply.github.com>

* Default to 100

* Revert "TESTING BRIDGE DENSITY"

This reverts commit 8634f802311cd3877b0dd5651029b30b2d4eab60.

Removed desc change

* Minor changes

Co-Authored-By: Noisyfox <timemanager.rick@gmail.com>

* Update LayerRegion.cpp

* Missing ;

* Restrict bridge line width to nozzle diameter

* Clarification

* Increased both Bridge Densitys to 125

Co-Authored-By: Valerii Bokhan <80919135+valerii-bokhan@users.noreply.github.com>

* Valerii check

Co-Authored-By: Valerii Bokhan <80919135+valerii-bokhan@users.noreply.github.com>

* Fix error handling

* Clarify thick bridges documentation and tooltips

Updated the documentation and tooltips for 'thick_bridges' and 'thick_internal_bridges' to clarify that bridge extrusion uses a line height equal to the nozzle diameter, and to better explain the trade-offs between strength, reliability, and appearance.

* Partially restore bridge_flow description

* Suggestions
