The format is almost identical to CL2, except it uses the frame header
to store frame width and height instead of 5 32-line offsets.
This means we always have access to frame dimensions, so we can use it
as an on-disk format for our graphics as well.
Additionally, we may be able to optimize the rendering even more
in the future now that we have guaranteed knowledge of frame dimensions.
Makes `CelSprite` unowned and adds a new `OwnedCelSprite` class for
owned sprites.
This clarifies ownership and makes the code cleaner in a number of
places.
Additionally, because the `CelSprite` class is now tiny (1 less
pointer), we can pass it by-value instead of by-reference, removing a
pointer indirection in the rendering functions.
Added overload for DrawString taking a Point to avoid creating a rect for callers which only use position. This also documents the way DrawString operates when passed a clipping rectangle with a dimension of 0.
As part of this overload removed the logic for 0 width regions from DrawString. This does change the behaviour of the Rectangle version if called with a rect with width 0, all callers using that behaviour have been updated in this commit.
Using Rectangle/Size allowed simplifying the logic for certain calls where they could use DrawText alignment flags, previously this was manually aligning by calculating dimensions and offsetting the position. This also fixes#2169
Also includes a few instances where a temporary buffer was used to set the text to be drawn with unbounded sprintf calls, replaced those with snprintf as is recommended in modern C applications. Moving to C++ strings would be good in a future refactor.
Given the program already lets the destructors get called naturally there's no need to explicitly call this function. Even if it was desirable to re-init the font data the old instances will be destroyed when the new instance is assigned to the optional.
This should gradually replace all the direct rendering of game texts
throughout the code. The interface is made to closly mirror that of the
art fonts as that is what will eventually be used for rendering Unicode
fonts both in the menus and ingame.
fixup! ✨ Generic game text render function
