Introduction of Graphics Abstraction Layer based rendering for pcbnew. New classes: - VIEW - represents view that is seen by user, takes care of layer ordering & visibility and how it is displayed (which location, how much zoomed, etc.) - VIEW_ITEM - Base class for every item that can be displayed on VIEW (the biggest change is that now it may be necessary to override ViewBBox & ViewGetLayers method for derived classes). - EDA_DRAW_PANEL_GAL - Inherits after EDA_DRAW_PANEL, displays VIEW output, right now it is not editable (in opposite to usual EDA_DRAW_PANEL). - GAL/OPENGL_GAL/CAIRO_GAL - Base Graphics Abstraction Layer class + two different flavours (Cairo is not fully supported yet), that offers methods to draw primitives using different libraries. - WX_VIEW_CONTROLS - Controller for VIEW, handles user events, allows zooming, panning, etc. - PAINTER/PCB_PAINTER - Classes that uses GAL interface to draw items (as you may have already guessed - PCB_PAINTER is a class for drawing PCB specific object, PAINTER is an abstract class). Its methods are invoked by VIEW, when an item has to be drawn. To display a new type of item - you need to implement draw(ITEM_TYPE*) method that draws it using GAL methods. - STROKE_FONT - Implements stroke font drawing using GAL methods. Most important changes to Kicad original code: * EDA_ITEM now inherits from VIEW_ITEM, which is a base class for all drawable objects. * EDA_DRAW_FRAME contains both usual EDA_DRAW_PANEL and new EDA_DRAW_PANEL_GAL, that can be switched anytime. * There are some new layers for displaying multilayer pads, vias & pads holes (these are not shown yet on the right sidebar in pcbnew) * Display order of layers is different than in previous versions (if you are curious - you may check m_galLayerOrder@pcbnew/basepcbframe.cpp). Preserving usual order would result in not very natural display, such as showing silkscreen texts on the bottom. * Introduced new hotkey (Alt+F12) and new menu option (View->Switch canvas) for switching canvas during runtime. * Some of classes (mostly derived from BOARD_ITEM) now includes ViewBBox & ViewGetLayers methods. * Removed tools/class_painter.h, as now it is extended and included in source code. Build changes: * GAL-based rendering option is turned on by a new compilation CMake option KICAD_GAL. * When compiling with CMake option KICAD_GAL=ON, GLEW and Cairo libraries are required. * GAL-related code is compiled into a static library (common/libgal). * Build with KICAD_GAL=OFF should not need any new libraries and should come out as a standard version of Kicad Currently most of items in pcbnew can be displayed using OpenGL (to be done are DIMENSIONS and MARKERS).
