Seth Hillbrand 3a3bbbb545 GAL: Add transparency for bitmaps and Cairo draw
Bitmaps loaded via wx can contain alpha channels.  We utilize underlying
routines to correctly map the alpha.  This also standardizes the Cairo
alpha calls to ensure correct display in Fallback for partially
transparent highlights

Seth Hillbrand e8333633fe GAL: Add antialiasing options to Cairo
Cairo supports antialiasing when rendering but can be slow when set to
sub-pixel mode.  This bumps the minimum version of Cairo to 1.12
(available in 14.04 LTS as well as mingw) to support three antialias
settings (fast, good, best) that offer speed/appearance tradeoffs.

This can provide a higher-quality eeschema render as it works on a
per-element basis as opposed to the OpenGL per-screen antialias.

jean-pierre charras db7dba96ad Fix a few Coverity warnings.
Mainly not initialized members, and replace not tested dynamic_cast by static_cast.

Maciej Suminski 64da77538f Fix bitmap scale in printouts
Display GALs had an incorrect world unit value set. Now the world unit
value says how many internal units are in an inch, in accord with the comments
in the GAL header. Bitmap drawing code relied on the information about DPI,
so scaling worked differently for display and print GALs.

Maciej Suminski e36f6b476d Changed the CAIRO_GAL class hierarchy
There is a dedicated class for display (CAIRO_GAL) and another one
for printing. The common part has been moved to CAIRO_GAL_BASE.

Maciej Suminski 5a64343fb4 CAIRO_PRINT_CTX class
CAIRO_PRINT_CTX provides a Cairo context created from wxPrintDC.
It allows one to prepare printouts using the Cairo library and
let wxWidgets handle the rest.

Jeff Young 16925cc74e Implement RAII locking for GAL updating.
Fixes a crash when typing fast in the place footprint filter box.

Also adds a bunch more checking to GAL locking, including making
sure the same person unlocks as locked, and preventing piece-meal
calls (the RAII objects must be used).

jean-pierre charras fefc7b8172 GAL canvases: add DrawBitmap(), using a basic brute force algo for OpenGL, and a optimized code for Cairo. In this fix the brute force means draw each pixel as a rectangle. It works fine, but could be optimized. 2018-07-30 00:13:30 +02:00
Maciej Suminski 7d9dea7897 Remove an excessive assert for Cairo canvas size
It is a C-style assert causing application termination when triggered.
Certain systems display pcbnew window shrinked so much, that the canvas
size is 0x0 pixels. The only problem with that is the window needs to be
resized.

Tomasz Włostowski 32185ddcd3 Multiple improvements concerning colors, configuration handling and legacy features in pcbnew:
- support for background color setting
    - removed several global config settings (such as g_Drc_On)
    - wrapped most of global config settings in PCB_GENERAL_SETTINGS class
    - reorganized PCB general options dialog to clearly mark which options concern only the legacy canvas
    - new GAL feature for legacy users: double-click (or E) to change track width available as an option.

Maciej Suminski ddf4f3b2bc Remove not used cursor fields & methods in Cairo GAL 2017-03-22 10:37:43 +01:00
John Beard b8edecc10f Move cursor shape flag into GAL settings
The motivation here is to concentrate display options in the GAL display
settings, ready for removal of legacy canvases. Instead of having the
property as a member of the DRAW_FRAME, with the GAL canvas retreiving
it from there, it is now in the GAL_DISPLAY_OPTIONS struct, and both GAL
and legacy get it from there.

The options for setting cursor shape are then moved out of the general
options dialog, and into the GAL display options widget, where they can
be used in all GAL-aware programs.

GAL cursor shape works on GAL, but not legacy, so the option is now
available on OSX (but only affects GAL, and is labelled as such).
