* Show header in font map files * fix a usage of unique_ptr with array * Added '--quiet' argument to hide progress messages (resolves #503) * Revert cout messages to cerr (see #622) * bump version * fix build; fix some coverity warnings * Many bug fixes and improvements, including: - Incorporated latest Cairo files from cairo-0.15.2 - Moved build to out-of-source - Added clean script - Rewritten correct_text_visibility option to improve accuracy - Transparent characters drawn on background layer - Improved bad unicode detection * Many bug fixes and improvements, including: - Incorporated latest Cairo files from cairo-0.15.2 - Moved build to out-of-source - Added clean script - Rewritten correct_text_visibility option to improve accuracy - Transparent characters drawn on background layer - Improved bad unicode detection * Rationlise DPI to single number. Implement actual_dpi - clamp maximum background image size in cases of huge PDF pages * DPI fixes - increase DPI when partially covered text to covered-text-dpi Add font-style italic for oblique fonts Reduce char bbox for occlusion tests * Don't shrink bbox - not required if zoom=25 used * Ignore occlusion from stroke/fill with opacity < 0.5 Better compute char bbox for occlusion Use 10% inset for char bbox for occlusion Back out adding font-weight: bold to potentially bold fonts Fix bug to ensure CID ascent/descent matches subfont values * Removed zero char logging * Remove forced italic - missing italic is due to fontforge bug which needs fixing * Typos fixed, readme updated * Typos * Increase maximum background image width Fix private use range to avoid stupid mobile safari switching to emoji font * included -pthread switch to link included 3rdparty poppler files. * Updated files from poppler 0.59.0 and adjusted includes. * Support updated "Object" class from poppler 0.59.0
