0.8.2

• Support multi-byte unicode characters in built-in layouts (only partially supported before).
• Optimise vertex generation allocation; gives a small worst-case performance boost.

0.8.1

Improve GPU texture cache performance by partitioning the glyph lookup table by font & glyph id.

0.8.0

• Update to gfx 0.17
• Update to log 0.4

0.7.0

• GlyphCalculator allows font calculations / pixel bounds etc without actually being able to draw anything, or the need for gfx objects. Using a scoped caching system.
• Update to rusttype 0.3.0
• Cache / font lifetime changes made to rusttype allow removing the .standalone() calls when adding glyphs to the gpu-cache. This and other rusttype optimisations can result in up to ~25% faster worst case performance (worst case being no position/draw caching / text changes every frame).
• OwnedVariedSection & OwnedSectionText to help some edge cases where borrowing is annoying.
• Simple Debug implementations to allow end users to derive more easily.

0.6.4

• Switch to OpenGL 3.2 / glsl 150 requirement to fix MacOS issues with glsl 130

I'm publishing as a minor increment even though this may break your setup if you relied on OpenGL < 3.2 support, but I don't think anyone actually does. Please get into contact if this broke your setup.

0.6.3

• Fix GlyphBrush being able to use cached vertices after a render resolution change.
• When dynamically increasing the gpu glyph texture warn and show a backtrace to allow this to be addressed when using many GlyphBrush instances.

0.6.2

Fix VariedSections with multiple SectionText parts ignoring end-of-line hard breaks.

0.6.1

Add GlyphBrush#glyphs & #glyphs_custom_layout methods to allow access to the PositionedGlyphs of a section.

0.6.0

• GlyphBrushBuilder supports Font types with using_font/add_font
• Renamed existing GlyphBrushBuilder methods -> using_font_bytes/add_font_bytes

0.5.1

Fix rare glyph ordering panic in gpu cache code
