* added commandlist at root panel level so we dont have 1 commandlist per panel * added codepath where panel renderer write to the panel roots commandlist instead of their one * added rcon to toggle between both at runtime * cache transform * Build flat commandlist for panels * added globalcommand list in UI system each rootpanel command list will be appended to this global commandlist so we reduce overhead while drawing. * removed debug Ui * gather children command lists * use Count instead of Count() - remove some other code * renamed FlatCommandList to PanelCommandlist removed more unused code * removed ref to cached transform * simply loop * remove useless line, remve unsafe keyword, remove should early cull * added separate profiling scope for building, gathering and executing command lists * forgot this * check if yoga layout rect has changed before setting is render dirty * dont need to draw this quad * Dont append scissor every frame as we cache them. * add seaprate scissor function that does append ot attributes only on rebuild * only update scissor attributes if it has changes, otherwise used cached commandlist * panel renderer check if panel has layer * only build transform commandlist if transform has changed, otherwise used the cached transforms * fixed some UI widgets not updating due to their opacity correctly. This is the bug where widgets wouldnt be visible until you hovered them * use span for iterating commandlists * dotnet format * async SVG and texture loading mark as dirty once loading is done * dont render UI panels flagged as render manually
