annotate engine/core/view/renderers/instancerenderer.h @ 589:d1df6cf5ff23

* Fixed a bug in RenderBackendSDL, the clip area was not properly set. * Renamed the backquad and border commands of the FloatingTextRenderer. * Added the TransparentArea commands to the InstanceRenderer. Note: with addTransparentArea(instance, string, width, height, transparent, front) you can enable an area, that make all instances in this zone and with the same namespace transparent. The string is for the namespace, so you can set one or more namespaces to be transparent. Width and height specifies the size of the area. Transparent defines the intensity of transparency, 255 = invisible. The bool front, enable or disable the z check, so that only instances in front of the source instance could be transparent.

edc9efe969c2 This commit should fix the coloring overlay bug exposed by the commit in revision 3386. The InstanceRenderer was caching the overlays based on whether the current image had changed. The fix takes into account the current image as well as the overlay color to decide whether or not the overlay needs to be reproduced.
