dd1676ad8a Add tolerance to center finding 
In some cases, the computation of valid sweep angle hit numerical limits
and no centers are found.

This commit adds a small amount of tolerance.

5b67c82abc Replace sys.maxint with sys.maxsize 
In Python 3, sys.maxint was removed, however its current use
can be safely substituted with sys.maxsize (also in Python 2)

965d3ce23b Add more tests for rendering to PNG. Start adding tests for rendering to Gerber format. Changed definition of no hole to use None instead of 0 so we can differentiate when writing to Gerber format.

5476da8aa3 Fix a bunch of rendering bugs. 
- 'clear' polarity primitives no longer erase background
  - Added aperture macro support for polygons
  - Added aperture macro rendring support
  - Renderer now creates a new surface for each layer and merges them instead of working
    directly on a single surface
  - Updated examples accordingly

2208fe2205 Fix issue when a region is created as the first graphical object in a file 
When regions were the first thing draw there is no current aperture
defined, as regions do not require an aperture, so we use an zeroed
Circle as aperture in this case. Gerber spec says that apertures have
no graphical meaning for regions, so this should be enough.

cb2fa34e88 Add support for arcs in regions. 
This fixes the circular cutout issue described in #32.  Regions were previously stored as a collection of points, now they are stored as a collection of line and arc primitives.

9e36d7e21d G70/G71 are now interpreted as MOParamStmt. 
Got a bunch of metric files with no MOMM but only G71, this
should be pretty mush harmless.

aff36a4dca Fix multiline read of mixed statements (%XXX*% followed by DNN*) 
We now check if there is a %XXX*% command inside the line before
considering it a multiline statement.

2fe5f36db2 Fix ADD statement parsing for concatened statements. 
ADDxxx param statements were too greedy on the mofidiers and were
matching more than it should in cases where there are no newlines after
the statement like:

'%ADD12C,0.305*%%LPD*%', in a single line. The '%' was not exluded form
modifiers so it got confused with the %LPD*% concatened.

top_copper.GTL example was changed to be in a single line now with no
spaces at all and it works well.

390838fc8b Fix for #25. Checking was happening at the gerber/excellon file level, but I added units checking at the primitive level so the use case shown in the example is covered. Might want to throw a bunch more assertions in the test code (i started doing a few) to cover multiple calls to unit conversion functions 2015-04-24 10:54:13 -04:00
