["David Michonneau" <dmichonneau@xxxxxxxxxxx>]

- Summary:

Improved Chart Rendering Quality

- Bugzilla Bug (s) Resolved:

117476 Poor Rendering Quality

- Description:

Corrected font sizes accross all device renderers

Improved font rendering for small fonts (disabled antialias), except for SVG (pending fix)

Enabled the user to choose the image format for PDF (previously always jpg)

Uses higher resolution (96*2) for PDF output

Dynamic dpi resolution enabled on device renderers with a new property (DPI_RESOLUTION)

Improved GIF rendering to use better colors and avoid dithering

Added API support to control Jpeg compression quality on Jpg renderer

Deprecated old PNG/GIF renderer implementations

Fixed a bug on GIF and PNG renderers regarding transparent color (rendered as black in unit tests previously)

Improved device renderers detection to avoid unnecessary exceptions

Updated Unit tests

- Tests Description : Unit tests.
