Issue description
As Synfig is primarily a graphics application so it would be ideal if the canvas displayed at the best quality possible. For my case I have a Retina Mac Book Pro. Retina is Apple's term to mean 2 screen pixels for every 1 window point in each direction, or 4 screen pixels area making up every window point. This is so that window elements stay the same size instead of being unreadably small, while graphics and text become twice as sharp. Windows laptops are starting to ship with high pixel density screens too (though not always 2pt to 1px). High pixel density screens are going to become more common, adding Retina support now would be future proofing.

In the current Mac native build handles and tools on the workspace are already Retina (and text too). This suggests that perhaps adding Retina support to the drawing canvas itself might not be too hard. However I know Inkscape is struggling with a Retina canvas, GIMP hasn't done it either, so I guess it could be a really hard thing to do.

Adding Retina support would slow down rendering 4X as there are 4X the pixels, so it might have to be an option, though there is already a low resolution mode so perhaps this would suffice.

Note: "Retina" is trademarked my Apple, though it is the term in common usage. For any official release with "Retina" support you would have to call it something else, like "High pixel density" "High DPI" "2X PPI" or something like that. CSS calls it "device-pixel-ratio: 2".

Hi. Thanks for the post. I also have a macbook. At the most inopportune moment the battery broke. Where can I find a decent replacement?

Don't forget to check the warranty and return policy before buying a battery. Some manufacturers offer long warranties on their products, which may be an important factor in your choice.

You may have noticed that your laptop is running slower, the battery is draining faster, or there are keyboard or display problems. When choosing a battery for your macbook, it's important to pay attention to its quality and reliability. It is better to buy a battery from a reliable manufacturer with a good reputation This will help avoid unpleasant surprises associated with a fast and worn out battery.

Before buying a new battery, make sure that it is fully compatible with your macbook model. Different models have different battery requirements, so it's important to choose the right model to avoid compatibility and installation issues.

One of the important factors when choosing a battery is its capacity and runtime. Pay attention to battery capacity, expressed in milliampere hours (mAh). The higher the mAh value, the longer your macbook will last without recharging. Choose the battery with the optimum capacity based on your needs.
