df2620838e Improve RefCell usage 
Use a RefCell only where we need it, in the glyph cache. We don't need
it for the platform data.

7807631ba0 Fix leaking texture atlas allocations 
When a rendering primitive holding a reference into a texture atlas
allocation is dropped, we should free that area for future re-use.

d6ef7c31a8 Fix rendering artifacts when scaling 
The use of the texture atlas may result in pixels from adjacent textures
bleeding into the currently rendered texture. The standard technique appears to be
to add a padding around each image.

ccb2e23cf5 Fix GL texture not freeing its texture id 
Similar to the shaders, keep a reference count on the resource itself and
keep the context around for convenient deletion.

Fixes: #3

6faf7439c2 Delete GL shader programs automatically 
We already keep the context in an RC, might as well keep another copy :-)

This re-applies commit 9b0dfa14b5 but
replaces the Clone trait on Shader, which would lead to duplicate and
too early program deletion, with an Rc<Shader>.

d9c776eb57 Revert "Delete GL shader programs automatically" 
This reverts commit 9b0dfa14b5 as there's
an issue with webgl and everything disappearing.

f86f8360b2 Fix rendering of text with spaces 
Don't waste glyphs and potential pixels from the rasterizer for space --
merely use the advance.

aecf6a8878 Center text in buttons in the demo and gallery 
This adds horizontal_alignment/vertical_alignment properties, along with
width/height to Text.

This still uses a hard-coded enumeration in the compiler, which is meant
to go away in favor of general enum support.

d3c596669c Add larger icons to the printer demo 
The icons on the main screen are now nicely large and they scale down on
activation.

48df8d0911 Rework the API between the items and the renderer 
Move fields out of the HighLevelRenderingPrimitive that are suitable to
represent as uniform variables. That reduces fields like Image or
Rectangle to their image or dimension, and only if *they* change, then
we re-do the work of building geometry and uploading it to the GPU.

Instead, the typically animated properties such as the position or the
color are passed separately with each draw call. This avoids re-decoding
PNG files and uploading them again when moving an image element around
on the screen.

a9297af00d Update the rendering primitives lazily using a property listener scope 
This also allows avoiding the need to store the high-level rendering
primitive item in the low-level primitive struct for comparison later.

685a3fb8ab Rename Text::font_pixel_size to just font_size 
Since length are resolution independent, it doesn't make sense anymore
to have the pixel infix.

2b713eb341 Use a default font size that scales with the window scale factor 
This is still coded in the backend but eventually we'll have default values
properties of items and then that can go there.

9938197b58 Split Rectangle again 
Into the previous Rectangle and BorderRectangle that allows (rounded) borders through a stroke in addition to the fill.

Next step is to make the compiler make the choice automatically depending
on the properties used.

dd9bd2cf72 Add a rounded border to the button 
There's still an open question about how to avoid the border properties
for all rectangles but allocate them only for those who have a border.
Regardless, this border illustrates the issue with the lack of text sizing.

992f990fa8 Allow for fitting paths into a given bounding rectangle 
... by applying a transformation. This allows designing a path in some
other path design tool and then make it fit using bindings.

6243df1702 Avoid unnecessary path building 
When the path was constructed from events (SVG commands), then we don't really need to build an intermediate path,
neither for rendering nor for path layouting.

c6c0f1f589 Make path arc rendering more robust 
Some arcs may not result in any content, for example if the radius is too small
or start and end pointer overlap. Let Lyon do the
checking for us and handle it accordingly.

Newer versions of Lyon will allow the re-use of the SvgArc created temporarily.

9cf2d618d2 Use Lyon's path builder 
Instead of trying to convert the individual (future) elements, let's use a builder.
This way the markup remains simple and due to
future support for bindings we can't really
pre-compute the path events anyway.
