Mingw, all: remove static link of libgcc, which can create issues when using dll version of wxWidgets.
Therefore libgcc_s_dw2-1.dll should be in the paths for executables.

add libglew-dev prerequisite for debian systems, it pulls in libgl1-mesa-dev and libglu1-mesa-dev on its own

Fixes missing worksheet layout when there is no PCB loaded and all random brightness changes for the Cairo rendering backend.

Pcbnew: Fix incorrect bounding box calculation of texts. Only noticeable with boards conveted from Eagle, which are using other text justification than center.
Eagle plugin: filter and replace not allowed chars in FPID(-':' and '/')  by _ or -, if they are used in Eagle footprint names (otherwise, boards converted and saved under kicad_pcb format are not readable by Pcbnew).

Disable patch from Baranovskiy Konstantin about vertical justification of multiline texts, because it does not work for rotated/mirrored texts

   pass into an HTML rendering panel and otherwise look goofey.
*) Implement BOARD::Move() can call it from EAGLE_PLUGIN::Load().
*) When USE_FP_LIB_TABLE, tolerate blank nicknames in FPIDs coming from eeschema.
   See the switch for this in pcbnew/netlist.cpp as ALLOW_PARTIAL_FPID.
*) Add an assert and a try catch block to figure out that View does not
   like some eagle pcb board.  bitset::set() is getting a -1 value and firing
   an exception.

Pcbnew, compiled with python support: Under windows, force python environment, if the folder python27_us is found in Kicad bin folder (<kicad>/bin, and if  python27_us environment is not fully set (i.e. if python27_us is not in the path, or if PYTHONPATH id not defined.)

<%s> being replaced with '%s' because the former in invisible in html panels.
Cure some compiler warnings.

Pcbnew: fix a crash when a non ascii char (i.e. a char having a code > 127) is found in a text (see Bug #1246340).
Could be only a temporary fix (tested only with French non ascii chars).

Add undo command to dxf file import. Change improper use of __WXDEBUG__ to DEBUG in class_board_connected_item.cpp.

Changed the used framebuffer object extension from ARB_framebuffer_object to EXT_framebuffer_object (compatibility reasons).
