[gtk] FontPlatformData contains more fields than required

• Component: New Bugs
• Status: RESOLVED FIXED

[Sven Herzberg]

FontPlatformData::setFont(cairo_t*) can be changed to use m_scaledFont directly. This makes the function easier readable and still works exactly as expected.

m_fontFace, m_fontMatrix, and m_options are used in the main constructor in FontPlatformDataGdk.cpp only then. So they should be turned into local variables instead of extra fields.

The attached patch-set reduces the memory footprint of each FontPlatformData by 3*sizeof(void*).

The only issue that's left is that the former fields are not renamed according the the code conventions in my patches, do you want another patch for that?

Some minor comments:
The local variables inside FontPlatformData::FontPlatformData should lose the m_ prefix, which is used only for members.  I think the declarations can be moved to their point of first use too.
Our coding style also requires no space between the function name and it's arguments.

I'll make those minor tweaks when I land this.
